Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460260, here are decompositions:

131 + 31460129 = 31460260
197 + 31460063 = 31460260
311 + 31459949 = 31460260
401 + 31459859 = 31460260
431 + 31459829 = 31460260
563 + 31459697 = 31460260
593 + 31459667 = 31460260
599 + 31459661 = 31460260

Showing the first eight; more decompositions exist.
