Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455832, here are decompositions:

3 + 31455829 = 31455832
11 + 31455821 = 31455832
29 + 31455803 = 31455832
71 + 31455761 = 31455832
131 + 31455701 = 31455832
311 + 31455521 = 31455832
383 + 31455449 = 31455832
461 + 31455371 = 31455832

Showing the first eight; more decompositions exist.
