Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610372, here are decompositions:

19 + 31610353 = 31610372
103 + 31610269 = 31610372
229 + 31610143 = 31610372
349 + 31610023 = 31610372
379 + 31609993 = 31610372
439 + 31609933 = 31610372
523 + 31609849 = 31610372
613 + 31609759 = 31610372

Showing the first eight; more decompositions exist.
