Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483350, here are decompositions:

23 + 31483327 = 31483350
37 + 31483313 = 31483350
43 + 31483307 = 31483350
89 + 31483261 = 31483350
113 + 31483237 = 31483350
137 + 31483213 = 31483350
181 + 31483169 = 31483350
233 + 31483117 = 31483350

Showing the first eight; more decompositions exist.
