Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484442, here are decompositions:

29 + 31484413 = 31484442
79 + 31484363 = 31484442
83 + 31484359 = 31484442
89 + 31484353 = 31484442
103 + 31484339 = 31484442
139 + 31484303 = 31484442
233 + 31484209 = 31484442
239 + 31484203 = 31484442

Showing the first eight; more decompositions exist.
