Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484340, here are decompositions:

23 + 31484317 = 31484340
37 + 31484303 = 31484340
59 + 31484281 = 31484340
73 + 31484267 = 31484340
101 + 31484239 = 31484340
103 + 31484237 = 31484340
131 + 31484209 = 31484340
137 + 31484203 = 31484340

Showing the first eight; more decompositions exist.
