Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460012, here are decompositions:

13 + 31459999 = 31460012
19 + 31459993 = 31460012
163 + 31459849 = 31460012
379 + 31459633 = 31460012
613 + 31459399 = 31460012
673 + 31459339 = 31460012
691 + 31459321 = 31460012
751 + 31459261 = 31460012

Showing the first eight; more decompositions exist.
