Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455964, here are decompositions:

3 + 31455961 = 31455964
5 + 31455959 = 31455964
17 + 31455947 = 31455964
251 + 31455713 = 31455964
263 + 31455701 = 31455964
317 + 31455647 = 31455964
431 + 31455533 = 31455964
443 + 31455521 = 31455964

Showing the first eight; more decompositions exist.
