Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529026, here are decompositions:

29 + 31528997 = 31529026
59 + 31528967 = 31529026
173 + 31528853 = 31529026
467 + 31528559 = 31529026
479 + 31528547 = 31529026
593 + 31528433 = 31529026
653 + 31528373 = 31529026
677 + 31528349 = 31529026

Showing the first eight; more decompositions exist.

IPv4 address
