Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452718, here are decompositions:

41 + 31452677 = 31452718
131 + 31452587 = 31452718
179 + 31452539 = 31452718
191 + 31452527 = 31452718
197 + 31452521 = 31452718
257 + 31452461 = 31452718
317 + 31452401 = 31452718
509 + 31452209 = 31452718

Showing the first eight; more decompositions exist.
