Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496744, here are decompositions:

3 + 31496741 = 31496744
67 + 31496677 = 31496744
73 + 31496671 = 31496744
151 + 31496593 = 31496744
157 + 31496587 = 31496744
193 + 31496551 = 31496744
373 + 31496371 = 31496744
523 + 31496221 = 31496744

Showing the first eight; more decompositions exist.
