Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610996, here are decompositions:

103 + 31610893 = 31610996
223 + 31610773 = 31610996
367 + 31610629 = 31610996
409 + 31610587 = 31610996
433 + 31610563 = 31610996
457 + 31610539 = 31610996
607 + 31610389 = 31610996
643 + 31610353 = 31610996

Showing the first eight; more decompositions exist.
