Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1548, here are decompositions:

  • 5 + 1543 = 1548
  • 17 + 1531 = 1548
  • 37 + 1511 = 1548
  • 59 + 1489 = 1548
  • 61 + 1487 = 1548
  • 67 + 1481 = 1548
  • 89 + 1459 = 1548
  • 97 + 1451 = 1548

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 1548 first appears in π at position 3,644 of the decimal expansion (the 3,644ordinal-suffix:th 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.
