Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499152, here are decompositions:

89 + 31499063 = 31499152
131 + 31499021 = 31499152
149 + 31499003 = 31499152
239 + 31498913 = 31499152
389 + 31498763 = 31499152
449 + 31498703 = 31499152
593 + 31498559 = 31499152
653 + 31498499 = 31499152

Showing the first eight; more decompositions exist.
