Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610882, here are decompositions:

103 + 31610779 = 31610882
109 + 31610773 = 31610882
241 + 31610641 = 31610882
313 + 31610569 = 31610882
379 + 31610503 = 31610882
613 + 31610269 = 31610882
739 + 31610143 = 31610882
769 + 31610113 = 31610882

Showing the first eight; more decompositions exist.
