Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536982, here are decompositions:

23 + 31536959 = 31536982
251 + 31536731 = 31536982
263 + 31536719 = 31536982
353 + 31536629 = 31536982
431 + 31536551 = 31536982
443 + 31536539 = 31536982
461 + 31536521 = 31536982
599 + 31536383 = 31536982

Showing the first eight; more decompositions exist.
