Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610966, here are decompositions:

73 + 31610893 = 31610966
193 + 31610773 = 31610966
337 + 31610629 = 31610966
379 + 31610587 = 31610966
397 + 31610569 = 31610966
463 + 31610503 = 31610966
577 + 31610389 = 31610966
613 + 31610353 = 31610966

Showing the first eight; more decompositions exist.
