Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610492, here are decompositions:

79 + 31610413 = 31610492
103 + 31610389 = 31610492
139 + 31610353 = 31610492
223 + 31610269 = 31610492
349 + 31610143 = 31610492
379 + 31610113 = 31610492
409 + 31610083 = 31610492
499 + 31609993 = 31610492

Showing the first eight; more decompositions exist.
