Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460264, here are decompositions:

67 + 31460197 = 31460264
97 + 31460167 = 31460264
127 + 31460137 = 31460264
211 + 31460053 = 31460264
271 + 31459993 = 31460264
373 + 31459891 = 31460264
457 + 31459807 = 31460264
541 + 31459723 = 31460264

Showing the first eight; more decompositions exist.
