Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484474, here are decompositions:

13 + 31484461 = 31484474
61 + 31484413 = 31484474
97 + 31484377 = 31484474
157 + 31484317 = 31484474
193 + 31484281 = 31484474
271 + 31484203 = 31484474
313 + 31484161 = 31484474
331 + 31484143 = 31484474

Showing the first eight; more decompositions exist.
