Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619136, here are decompositions:

7 + 31619129 = 31619136
13 + 31619123 = 31619136
19 + 31619117 = 31619136
127 + 31619009 = 31619136
137 + 31618999 = 31619136
193 + 31618943 = 31619136
239 + 31618897 = 31619136
257 + 31618879 = 31619136

Showing the first eight; more decompositions exist.
