Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31518674, here are decompositions:

67 + 31518607 = 31518674
73 + 31518601 = 31518674
151 + 31518523 = 31518674
193 + 31518481 = 31518674
223 + 31518451 = 31518674
331 + 31518343 = 31518674
373 + 31518301 = 31518674
613 + 31518061 = 31518674

Showing the first eight; more decompositions exist.
