Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492546, here are decompositions:

5 + 31492541 = 31492546
17 + 31492529 = 31492546
53 + 31492493 = 31492546
227 + 31492319 = 31492546
269 + 31492277 = 31492546
383 + 31492163 = 31492546
389 + 31492157 = 31492546
467 + 31492079 = 31492546

Showing the first eight; more decompositions exist.
