Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610282, here are decompositions:

3 + 31610279 = 31610282
13 + 31610269 = 31610282
139 + 31610143 = 31610282
199 + 31610083 = 31610282
271 + 31610011 = 31610282
349 + 31609933 = 31610282
421 + 31609861 = 31610282
433 + 31609849 = 31610282

Showing the first eight; more decompositions exist.
