Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550486, here are decompositions:

7 + 31550479 = 31550486
157 + 31550329 = 31550486
199 + 31550287 = 31550486
229 + 31550257 = 31550486
307 + 31550179 = 31550486
337 + 31550149 = 31550486
349 + 31550137 = 31550486
367 + 31550119 = 31550486

Showing the first eight; more decompositions exist.
