Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566046, here are decompositions:

3 + 31566043 = 31566046
53 + 31565993 = 31566046
353 + 31565693 = 31566046
383 + 31565663 = 31566046
443 + 31565603 = 31566046
647 + 31565399 = 31566046
797 + 31565249 = 31566046
839 + 31565207 = 31566046

Showing the first eight; more decompositions exist.
