Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610756, here are decompositions:

127 + 31610629 = 31610756
193 + 31610563 = 31610756
367 + 31610389 = 31610756
439 + 31610317 = 31610756
487 + 31610269 = 31610756
613 + 31610143 = 31610756
643 + 31610113 = 31610756
673 + 31610083 = 31610756

Showing the first eight; more decompositions exist.
