Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492624, here are decompositions:

47 + 31492577 = 31492624
71 + 31492553 = 31492624
83 + 31492541 = 31492624
131 + 31492493 = 31492624
347 + 31492277 = 31492624
461 + 31492163 = 31492624
467 + 31492157 = 31492624
557 + 31492067 = 31492624

Showing the first eight; more decompositions exist.
