Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484438, here are decompositions:

61 + 31484377 = 31484438
79 + 31484359 = 31484438
157 + 31484281 = 31484438
199 + 31484239 = 31484438
229 + 31484209 = 31484438
277 + 31484161 = 31484438
367 + 31484071 = 31484438
379 + 31484059 = 31484438

Showing the first eight; more decompositions exist.
