Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452762, here are decompositions:

13 + 31452749 = 31452762
23 + 31452739 = 31452762
31 + 31452731 = 31452762
41 + 31452721 = 31452762
43 + 31452719 = 31452762
79 + 31452683 = 31452762
113 + 31452649 = 31452762
139 + 31452623 = 31452762

Showing the first eight; more decompositions exist.
