Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588626, here are decompositions:

19 + 31588607 = 31588626
23 + 31588603 = 31588626
103 + 31588523 = 31588626
163 + 31588463 = 31588626
227 + 31588399 = 31588626
257 + 31588369 = 31588626
269 + 31588357 = 31588626
313 + 31588313 = 31588626

Showing the first eight; more decompositions exist.
