Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31566104, here are decompositions:

43 + 31566061 = 31566104
61 + 31566043 = 31566104
103 + 31566001 = 31566104
151 + 31565953 = 31566104
313 + 31565791 = 31566104
433 + 31565671 = 31566104
607 + 31565497 = 31566104
613 + 31565491 = 31566104

Showing the first eight; more decompositions exist.
