Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492054, here are decompositions:

3 + 31492051 = 31492054
23 + 31492031 = 31492054
71 + 31491983 = 31492054
137 + 31491917 = 31492054
173 + 31491881 = 31492054
263 + 31491791 = 31492054
317 + 31491737 = 31492054
467 + 31491587 = 31492054

Showing the first eight; more decompositions exist.
