Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484678, here are decompositions:

31 + 31484647 = 31484678
61 + 31484617 = 31484678
109 + 31484569 = 31484678
229 + 31484449 = 31484678
397 + 31484281 = 31484678
439 + 31484239 = 31484678
499 + 31484179 = 31484678
607 + 31484071 = 31484678

Showing the first eight; more decompositions exist.
