Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460138, here are decompositions:

139 + 31459999 = 31460138
331 + 31459807 = 31460138
379 + 31459759 = 31460138
421 + 31459717 = 31460138
487 + 31459651 = 31460138
739 + 31459399 = 31460138
751 + 31459387 = 31460138
877 + 31459261 = 31460138

Showing the first eight; more decompositions exist.
