Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496562, here are decompositions:

11 + 31496551 = 31496562
23 + 31496539 = 31496562
43 + 31496519 = 31496562
73 + 31496489 = 31496562
113 + 31496449 = 31496562
173 + 31496389 = 31496562
191 + 31496371 = 31496562
193 + 31496369 = 31496562

Showing the first eight; more decompositions exist.
