Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484532, here are decompositions:

19 + 31484513 = 31484532
29 + 31484503 = 31484532
71 + 31484461 = 31484532
83 + 31484449 = 31484532
173 + 31484359 = 31484532
179 + 31484353 = 31484532
193 + 31484339 = 31484532
229 + 31484303 = 31484532

Showing the first eight; more decompositions exist.
