Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450262, here are decompositions:

43 + 31450219 = 31450262
163 + 31450099 = 31450262
229 + 31450033 = 31450262
241 + 31450021 = 31450262
271 + 31449991 = 31450262
331 + 31449931 = 31450262
409 + 31449853 = 31450262
439 + 31449823 = 31450262

Showing the first eight; more decompositions exist.
