Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610946, here are decompositions:

53 + 31610893 = 31610946
79 + 31610867 = 31610946
167 + 31610779 = 31610946
173 + 31610773 = 31610946
223 + 31610723 = 31610946
239 + 31610707 = 31610946
307 + 31610639 = 31610946
317 + 31610629 = 31610946

Showing the first eight; more decompositions exist.
