Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606118, here are decompositions:

31 + 31606087 = 31606118
67 + 31606051 = 31606118
241 + 31605877 = 31606118
307 + 31605811 = 31606118
337 + 31605781 = 31606118
421 + 31605697 = 31606118
499 + 31605619 = 31606118
541 + 31605577 = 31606118

Showing the first eight; more decompositions exist.
