Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499564, here are decompositions:

3 + 31499561 = 31499564
67 + 31499497 = 31499564
73 + 31499491 = 31499564
97 + 31499467 = 31499564
157 + 31499407 = 31499564
163 + 31499401 = 31499564
181 + 31499383 = 31499564
193 + 31499371 = 31499564

Showing the first eight; more decompositions exist.
