Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536790, here are decompositions:

17 + 31536773 = 31536790
59 + 31536731 = 31536790
71 + 31536719 = 31536790
83 + 31536707 = 31536790
239 + 31536551 = 31536790
251 + 31536539 = 31536790
269 + 31536521 = 31536790
431 + 31536359 = 31536790

Showing the first eight; more decompositions exist.
