Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462432, here are decompositions:

59 + 31462373 = 31462432
83 + 31462349 = 31462432
509 + 31461923 = 31462432
641 + 31461791 = 31462432
653 + 31461779 = 31462432
863 + 31461569 = 31462432
1019 + 31461413 = 31462432
1091 + 31461341 = 31462432

Showing the first eight; more decompositions exist.
