Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484798, here are decompositions:

151 + 31484647 = 31484798
181 + 31484617 = 31484798
229 + 31484569 = 31484798
337 + 31484461 = 31484798
349 + 31484449 = 31484798
421 + 31484377 = 31484798
439 + 31484359 = 31484798
619 + 31484179 = 31484798

Showing the first eight; more decompositions exist.
