Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473836, here are decompositions:

103 + 31473733 = 31473836
307 + 31473529 = 31473836
313 + 31473523 = 31473836
349 + 31473487 = 31473836
379 + 31473457 = 31473836
439 + 31473397 = 31473836
523 + 31473313 = 31473836
619 + 31473217 = 31473836

Showing the first eight; more decompositions exist.
