Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484888, here are decompositions:

67 + 31484821 = 31484888
241 + 31484647 = 31484888
271 + 31484617 = 31484888
439 + 31484449 = 31484888
571 + 31484317 = 31484888
607 + 31484281 = 31484888
709 + 31484179 = 31484888
727 + 31484161 = 31484888

Showing the first eight; more decompositions exist.
