Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536690, here are decompositions:

61 + 31536629 = 31536690
83 + 31536607 = 31536690
139 + 31536551 = 31536690
151 + 31536539 = 31536690
191 + 31536499 = 31536690
293 + 31536397 = 31536690
307 + 31536383 = 31536690
331 + 31536359 = 31536690

Showing the first eight; more decompositions exist.
