Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499674, here are decompositions:

53 + 31499621 = 31499674
113 + 31499561 = 31499674
137 + 31499537 = 31499674
263 + 31499411 = 31499674
347 + 31499327 = 31499674
383 + 31499291 = 31499674
443 + 31499231 = 31499674
491 + 31499183 = 31499674

Showing the first eight; more decompositions exist.
