Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31445696, here are decompositions:

3 + 31445693 = 31445696
19 + 31445677 = 31445696
109 + 31445587 = 31445696
157 + 31445539 = 31445696
277 + 31445419 = 31445696
433 + 31445263 = 31445696
463 + 31445233 = 31445696
523 + 31445173 = 31445696

Showing the first eight; more decompositions exist.
