Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499362, here are decompositions:

53 + 31499309 = 31499362
71 + 31499291 = 31499362
131 + 31499231 = 31499362
173 + 31499189 = 31499362
179 + 31499183 = 31499362
359 + 31499003 = 31499362
431 + 31498931 = 31499362
449 + 31498913 = 31499362

Showing the first eight; more decompositions exist.
