Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450332, here are decompositions:

19 + 31450313 = 31450332
41 + 31450291 = 31450332
61 + 31450271 = 31450332
113 + 31450219 = 31450332
191 + 31450141 = 31450332
229 + 31450103 = 31450332
233 + 31450099 = 31450332
239 + 31450093 = 31450332

Showing the first eight; more decompositions exist.
