Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450696, here are decompositions:

29 + 31450667 = 31450696
83 + 31450613 = 31450696
107 + 31450589 = 31450696
113 + 31450583 = 31450696
269 + 31450427 = 31450696
383 + 31450313 = 31450696
449 + 31450247 = 31450696
479 + 31450217 = 31450696

Showing the first eight; more decompositions exist.
