Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484580, here are decompositions:

11 + 31484569 = 31484580
37 + 31484543 = 31484580
47 + 31484533 = 31484580
67 + 31484513 = 31484580
131 + 31484449 = 31484580
163 + 31484417 = 31484580
167 + 31484413 = 31484580
227 + 31484353 = 31484580

Showing the first eight; more decompositions exist.
