Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536748, here are decompositions:

17 + 31536731 = 31536748
29 + 31536719 = 31536748
41 + 31536707 = 31536748
197 + 31536551 = 31536748
227 + 31536521 = 31536748
389 + 31536359 = 31536748
401 + 31536347 = 31536748
461 + 31536287 = 31536748

Showing the first eight; more decompositions exist.
