Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492236, here are decompositions:

23 + 31492213 = 31492236
73 + 31492163 = 31492236
79 + 31492157 = 31492236
157 + 31492079 = 31492236
163 + 31492073 = 31492236
277 + 31491959 = 31492236
443 + 31491793 = 31492236
449 + 31491787 = 31492236

Showing the first eight; more decompositions exist.
