Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610462, here are decompositions:

73 + 31610389 = 31610462
109 + 31610353 = 31610462
193 + 31610269 = 31610462
349 + 31610113 = 31610462
379 + 31610083 = 31610462
439 + 31610023 = 31610462
601 + 31609861 = 31610462
613 + 31609849 = 31610462

Showing the first eight; more decompositions exist.
