Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610264, here are decompositions:

67 + 31610197 = 31610264
151 + 31610113 = 31610264
157 + 31610107 = 31610264
181 + 31610083 = 31610264
241 + 31610023 = 31610264
271 + 31609993 = 31610264
307 + 31609957 = 31610264
331 + 31609933 = 31610264

Showing the first eight; more decompositions exist.
