Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539076, here are decompositions:

3 + 31539073 = 31539076
29 + 31539047 = 31539076
89 + 31538987 = 31539076
269 + 31538807 = 31539076
347 + 31538729 = 31539076
383 + 31538693 = 31539076
587 + 31538489 = 31539076
599 + 31538477 = 31539076

Showing the first eight; more decompositions exist.
