Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450766, here are decompositions:

3 + 31450763 = 31450766
43 + 31450723 = 31450766
163 + 31450603 = 31450766
223 + 31450543 = 31450766
283 + 31450483 = 31450766
337 + 31450429 = 31450766
379 + 31450387 = 31450766
397 + 31450369 = 31450766

Showing the first eight; more decompositions exist.
