Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482632, here are decompositions:

19 + 31482613 = 31482632
73 + 31482559 = 31482632
193 + 31482439 = 31482632
283 + 31482349 = 31482632
463 + 31482169 = 31482632
619 + 31482013 = 31482632
733 + 31481899 = 31482632
919 + 31481713 = 31482632

Showing the first eight; more decompositions exist.
