Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461510, here are decompositions:

23 + 31461487 = 31461510
29 + 31461481 = 31461510
53 + 31461457 = 31461510
83 + 31461427 = 31461510
97 + 31461413 = 31461510
107 + 31461403 = 31461510
149 + 31461361 = 31461510
167 + 31461343 = 31461510

Showing the first eight; more decompositions exist.
