Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490534, here are decompositions:

7 + 31490527 = 31490534
37 + 31490497 = 31490534
73 + 31490461 = 31490534
151 + 31490383 = 31490534
157 + 31490377 = 31490534
211 + 31490323 = 31490534
277 + 31490257 = 31490534
307 + 31490227 = 31490534

Showing the first eight; more decompositions exist.
