Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931490, here are decompositions:

3 + 931487 = 931490
73 + 931417 = 931490
103 + 931387 = 931490
127 + 931363 = 931490
139 + 931351 = 931490
181 + 931309 = 931490
223 + 931267 = 931490
277 + 931213 = 931490

Showing the first eight; more decompositions exist.
