Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539124, here are decompositions:

41 + 31539083 = 31539124
137 + 31538987 = 31539124
173 + 31538951 = 31539124
317 + 31538807 = 31539124
431 + 31538693 = 31539124
563 + 31538561 = 31539124
647 + 31538477 = 31539124
797 + 31538327 = 31539124

Showing the first eight; more decompositions exist.
