Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500076, here are decompositions:

29 + 31500047 = 31500076
53 + 31500023 = 31500076
59 + 31500017 = 31500076
137 + 31499939 = 31500076
233 + 31499843 = 31500076
617 + 31499459 = 31500076
677 + 31499399 = 31500076
809 + 31499267 = 31500076

Showing the first eight; more decompositions exist.
