Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484412, here are decompositions:

53 + 31484359 = 31484412
59 + 31484353 = 31484412
73 + 31484339 = 31484412
109 + 31484303 = 31484412
131 + 31484281 = 31484412
173 + 31484239 = 31484412
233 + 31484179 = 31484412
251 + 31484161 = 31484412

Showing the first eight; more decompositions exist.
