Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536738, here are decompositions:

5 + 31536733 = 31536738
7 + 31536731 = 31536738
19 + 31536719 = 31536738
31 + 31536707 = 31536738
41 + 31536697 = 31536738
109 + 31536629 = 31536738
131 + 31536607 = 31536738
199 + 31536539 = 31536738

Showing the first eight; more decompositions exist.
