Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574260, here are decompositions:

59 + 31574201 = 31574260
167 + 31574093 = 31574260
239 + 31574021 = 31574260
293 + 31573967 = 31574260
401 + 31573859 = 31574260
467 + 31573793 = 31574260
503 + 31573757 = 31574260
563 + 31573697 = 31574260

Showing the first eight; more decompositions exist.
