Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454236, here are decompositions:

17 + 31454219 = 31454236
89 + 31454147 = 31454236
113 + 31454123 = 31454236
239 + 31453997 = 31454236
293 + 31453943 = 31454236
353 + 31453883 = 31454236
503 + 31453733 = 31454236
509 + 31453727 = 31454236

Showing the first eight; more decompositions exist.
