Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551846, here are decompositions:

19 + 31551827 = 31551846
43 + 31551803 = 31551846
89 + 31551757 = 31551846
113 + 31551733 = 31551846
163 + 31551683 = 31551846
233 + 31551613 = 31551846
269 + 31551577 = 31551846
307 + 31551539 = 31551846

Showing the first eight; more decompositions exist.
