Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501696, here are decompositions:

113 + 31501583 = 31501696
173 + 31501523 = 31501696
263 + 31501433 = 31501696
269 + 31501427 = 31501696
293 + 31501403 = 31501696
383 + 31501313 = 31501696
449 + 31501247 = 31501696
467 + 31501229 = 31501696

Showing the first eight; more decompositions exist.
