Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496732, here are decompositions:

13 + 31496719 = 31496732
61 + 31496671 = 31496732
139 + 31496593 = 31496732
181 + 31496551 = 31496732
193 + 31496539 = 31496732
283 + 31496449 = 31496732
313 + 31496419 = 31496732
439 + 31496293 = 31496732

Showing the first eight; more decompositions exist.
