Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500132, here are decompositions:

19 + 31500113 = 31500132
31 + 31500101 = 31500132
109 + 31500023 = 31500132
193 + 31499939 = 31500132
199 + 31499933 = 31500132
211 + 31499921 = 31500132
233 + 31499899 = 31500132
239 + 31499893 = 31500132

Showing the first eight; more decompositions exist.
