Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551046, here are decompositions:

47 + 31550999 = 31551046
53 + 31550993 = 31551046
167 + 31550879 = 31551046
179 + 31550867 = 31551046
239 + 31550807 = 31551046
347 + 31550699 = 31551046
419 + 31550627 = 31551046
503 + 31550543 = 31551046

Showing the first eight; more decompositions exist.
