Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551058, here are decompositions:

47 + 31551011 = 31551058
59 + 31550999 = 31551058
137 + 31550921 = 31551058
179 + 31550879 = 31551058
191 + 31550867 = 31551058
251 + 31550807 = 31551058
257 + 31550801 = 31551058
311 + 31550747 = 31551058

Showing the first eight; more decompositions exist.
