Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460482, here are decompositions:

41 + 31460441 = 31460482
83 + 31460399 = 31460482
113 + 31460369 = 31460482
191 + 31460291 = 31460482
353 + 31460129 = 31460482
419 + 31460063 = 31460482
653 + 31459829 = 31460482
773 + 31459709 = 31460482

Showing the first eight; more decompositions exist.
