Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499710, here are decompositions:

89 + 31499621 = 31499710
149 + 31499561 = 31499710
173 + 31499537 = 31499710
251 + 31499459 = 31499710
311 + 31499399 = 31499710
383 + 31499327 = 31499710
401 + 31499309 = 31499710
419 + 31499291 = 31499710

Showing the first eight; more decompositions exist.
