Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566124, here are decompositions:

41 + 31566083 = 31566124
47 + 31566077 = 31566124
131 + 31565993 = 31566124
353 + 31565771 = 31566124
431 + 31565693 = 31566124
461 + 31565663 = 31566124
521 + 31565603 = 31566124
563 + 31565561 = 31566124

Showing the first eight; more decompositions exist.
