Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524086, here are decompositions:

37 + 31524049 = 31524086
43 + 31524043 = 31524086
73 + 31524013 = 31524086
283 + 31523803 = 31524086
337 + 31523749 = 31524086
379 + 31523707 = 31524086
439 + 31523647 = 31524086
487 + 31523599 = 31524086

Showing the first eight; more decompositions exist.
