Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460944, here are decompositions:

17 + 31460927 = 31460944
71 + 31460873 = 31460944
107 + 31460837 = 31460944
113 + 31460831 = 31460944
227 + 31460717 = 31460944
461 + 31460483 = 31460944
503 + 31460441 = 31460944
653 + 31460291 = 31460944

Showing the first eight; more decompositions exist.
