Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483428, here are decompositions:

37 + 31483391 = 31483428
59 + 31483369 = 31483428
101 + 31483327 = 31483428
167 + 31483261 = 31483428
191 + 31483237 = 31483428
199 + 31483229 = 31483428
211 + 31483217 = 31483428
311 + 31483117 = 31483428

Showing the first eight; more decompositions exist.
