Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450396, here are decompositions:

83 + 31450313 = 31450396
149 + 31450247 = 31450396
179 + 31450217 = 31450396
233 + 31450163 = 31450396
293 + 31450103 = 31450396
353 + 31450043 = 31450396
827 + 31449569 = 31450396
839 + 31449557 = 31450396

Showing the first eight; more decompositions exist.
