Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550832, here are decompositions:

29 + 31550803 = 31550832
31 + 31550801 = 31550832
41 + 31550791 = 31550832
101 + 31550731 = 31550832
109 + 31550723 = 31550832
151 + 31550681 = 31550832
233 + 31550599 = 31550832
239 + 31550593 = 31550832

Showing the first eight; more decompositions exist.
