Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460144, here are decompositions:

7 + 31460137 = 31460144
127 + 31460017 = 31460144
151 + 31459993 = 31460144
181 + 31459963 = 31460144
337 + 31459807 = 31460144
421 + 31459723 = 31460144
523 + 31459621 = 31460144
757 + 31459387 = 31460144

Showing the first eight; more decompositions exist.
