Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566052, here are decompositions:

59 + 31565993 = 31566052
71 + 31565981 = 31566052
83 + 31565969 = 31566052
281 + 31565771 = 31566052
359 + 31565693 = 31566052
389 + 31565663 = 31566052
449 + 31565603 = 31566052
491 + 31565561 = 31566052

Showing the first eight; more decompositions exist.
