Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500088, here are decompositions:

5 + 31500083 = 31500088
41 + 31500047 = 31500088
71 + 31500017 = 31500088
149 + 31499939 = 31500088
167 + 31499921 = 31500088
467 + 31499621 = 31500088
677 + 31499411 = 31500088
701 + 31499387 = 31500088

Showing the first eight; more decompositions exist.
