Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450434, here are decompositions:

5 + 31450429 = 31450434
7 + 31450427 = 31450434
11 + 31450423 = 31450434
13 + 31450421 = 31450434
23 + 31450411 = 31450434
47 + 31450387 = 31450434
83 + 31450351 = 31450434
163 + 31450271 = 31450434

Showing the first eight; more decompositions exist.
