Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452598, here are decompositions:

11 + 31452587 = 31452598
59 + 31452539 = 31452598
71 + 31452527 = 31452598
101 + 31452497 = 31452598
137 + 31452461 = 31452598
179 + 31452419 = 31452598
197 + 31452401 = 31452598
257 + 31452341 = 31452598

Showing the first eight; more decompositions exist.
