Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610132, here are decompositions:

19 + 31610113 = 31610132
109 + 31610023 = 31610132
139 + 31609993 = 31610132
199 + 31609933 = 31610132
271 + 31609861 = 31610132
283 + 31609849 = 31610132
313 + 31609819 = 31610132
373 + 31609759 = 31610132

Showing the first eight; more decompositions exist.
