Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465060, here are decompositions:

113 + 31464947 = 31465060
233 + 31464827 = 31465060
239 + 31464821 = 31465060
251 + 31464809 = 31465060
359 + 31464701 = 31465060
443 + 31464617 = 31465060
479 + 31464581 = 31465060
503 + 31464557 = 31465060

Showing the first eight; more decompositions exist.
