Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460468, here are decompositions:

37 + 31460431 = 31460468
139 + 31460329 = 31460468
271 + 31460197 = 31460468
331 + 31460137 = 31460468
577 + 31459891 = 31460468
619 + 31459849 = 31460468
661 + 31459807 = 31460468
709 + 31459759 = 31460468

Showing the first eight; more decompositions exist.
