Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499848, here are decompositions:

5 + 31499843 = 31499848
137 + 31499711 = 31499848
227 + 31499621 = 31499848
311 + 31499537 = 31499848
389 + 31499459 = 31499848
449 + 31499399 = 31499848
461 + 31499387 = 31499848
521 + 31499327 = 31499848

Showing the first eight; more decompositions exist.
