Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550696, here are decompositions:

97 + 31550599 = 31550696
103 + 31550593 = 31550696
109 + 31550587 = 31550696
127 + 31550569 = 31550696
139 + 31550557 = 31550696
157 + 31550539 = 31550696
367 + 31550329 = 31550696
409 + 31550287 = 31550696

Showing the first eight; more decompositions exist.
