Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500052, here are decompositions:

5 + 31500047 = 31500052
29 + 31500023 = 31500052
113 + 31499939 = 31500052
131 + 31499921 = 31500052
431 + 31499621 = 31500052
491 + 31499561 = 31500052
593 + 31499459 = 31500052
641 + 31499411 = 31500052

Showing the first eight; more decompositions exist.
