Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536910, here are decompositions:

47 + 31536863 = 31536910
89 + 31536821 = 31536910
137 + 31536773 = 31536910
179 + 31536731 = 31536910
191 + 31536719 = 31536910
281 + 31536629 = 31536910
359 + 31536551 = 31536910
389 + 31536521 = 31536910

Showing the first eight; more decompositions exist.
