Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452658, here are decompositions:

59 + 31452599 = 31452658
71 + 31452587 = 31452658
131 + 31452527 = 31452658
137 + 31452521 = 31452658
197 + 31452461 = 31452658
239 + 31452419 = 31452658
257 + 31452401 = 31452658
317 + 31452341 = 31452658

Showing the first eight; more decompositions exist.
