Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80072, here are decompositions:

  • 73 + 79999 = 80072
  • 199 + 79873 = 80072
  • 211 + 79861 = 80072
  • 229 + 79843 = 80072
  • 271 + 79801 = 80072
  • 373 + 79699 = 80072
  • 379 + 79693 = 80072
  • 439 + 79633 = 80072

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 80072 first appears in π at position 145,893 of the decimal expansion (the 145,893ordinal-suffix:rd 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.
