Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1478, here are decompositions:

  • 7 + 1471 = 1478
  • 19 + 1459 = 1478
  • 31 + 1447 = 1478
  • 79 + 1399 = 1478
  • 97 + 1381 = 1478
  • 151 + 1327 = 1478
  • 157 + 1321 = 1478
  • 181 + 1297 = 1478

Showing the first eight; more decompositions exist.

Banks operate many routing numbers per state and division; an unmatched checksum-valid number can still be a real RTN at a smaller institution.

Position in π

The digit sequence 1478 first appears in π at position 9,492 of the decimal expansion (the 9,492ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
