Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519348, here are decompositions:

41 + 31519307 = 31519348
59 + 31519289 = 31519348
101 + 31519247 = 31519348
137 + 31519211 = 31519348
149 + 31519199 = 31519348
167 + 31519181 = 31519348
197 + 31519151 = 31519348
227 + 31519121 = 31519348

Showing the first eight; more decompositions exist.
