Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484846, here are decompositions:

7 + 31484839 = 31484846
199 + 31484647 = 31484846
229 + 31484617 = 31484846
277 + 31484569 = 31484846
313 + 31484533 = 31484846
397 + 31484449 = 31484846
433 + 31484413 = 31484846
487 + 31484359 = 31484846

Showing the first eight; more decompositions exist.
