Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460132, here are decompositions:

3 + 31460129 = 31460132
79 + 31460053 = 31460132
139 + 31459993 = 31460132
241 + 31459891 = 31460132
283 + 31459849 = 31460132
373 + 31459759 = 31460132
409 + 31459723 = 31460132
499 + 31459633 = 31460132

Showing the first eight; more decompositions exist.
