Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460150, here are decompositions:

13 + 31460137 = 31460150
97 + 31460053 = 31460150
151 + 31459999 = 31460150
157 + 31459993 = 31460150
433 + 31459717 = 31460150
499 + 31459651 = 31460150
541 + 31459609 = 31460150
751 + 31459399 = 31460150

Showing the first eight; more decompositions exist.
