Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467582, here are decompositions:

11 + 31467571 = 31467582
23 + 31467559 = 31467582
31 + 31467551 = 31467582
43 + 31467539 = 31467582
73 + 31467509 = 31467582
79 + 31467503 = 31467582
101 + 31467481 = 31467582
149 + 31467433 = 31467582

Showing the first eight; more decompositions exist.
