Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484618, here are decompositions:

157 + 31484461 = 31484618
241 + 31484377 = 31484618
337 + 31484281 = 31484618
379 + 31484239 = 31484618
409 + 31484209 = 31484618
439 + 31484179 = 31484618
457 + 31484161 = 31484618
547 + 31484071 = 31484618

Showing the first eight; more decompositions exist.
