Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550488, here are decompositions:

17 + 31550471 = 31550488
29 + 31550459 = 31550488
41 + 31550447 = 31550488
131 + 31550357 = 31550488
149 + 31550339 = 31550488
311 + 31550177 = 31550488
461 + 31550027 = 31550488
467 + 31550021 = 31550488

Showing the first eight; more decompositions exist.
