Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610270, here are decompositions:

73 + 31610197 = 31610270
127 + 31610143 = 31610270
157 + 31610113 = 31610270
163 + 31610107 = 31610270
277 + 31609993 = 31610270
313 + 31609957 = 31610270
337 + 31609933 = 31610270
409 + 31609861 = 31610270

Showing the first eight; more decompositions exist.
