Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566854, here are decompositions:

37 + 31566817 = 31566854
61 + 31566793 = 31566854
223 + 31566631 = 31566854
307 + 31566547 = 31566854
313 + 31566541 = 31566854
331 + 31566523 = 31566854
337 + 31566517 = 31566854
367 + 31566487 = 31566854

Showing the first eight; more decompositions exist.
