Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536760, here are decompositions:

29 + 31536731 = 31536760
41 + 31536719 = 31536760
53 + 31536707 = 31536760
131 + 31536629 = 31536760
239 + 31536521 = 31536760
401 + 31536359 = 31536760
467 + 31536293 = 31536760
557 + 31536203 = 31536760

Showing the first eight; more decompositions exist.
