Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462516, here are decompositions:

83 + 31462433 = 31462516
167 + 31462349 = 31462516
227 + 31462289 = 31462516
383 + 31462133 = 31462516
389 + 31462127 = 31462516
509 + 31462007 = 31462516
593 + 31461923 = 31462516
773 + 31461743 = 31462516

Showing the first eight; more decompositions exist.
