Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450562, here are decompositions:

19 + 31450543 = 31450562
79 + 31450483 = 31450562
139 + 31450423 = 31450562
151 + 31450411 = 31450562
193 + 31450369 = 31450562
211 + 31450351 = 31450562
271 + 31450291 = 31450562
421 + 31450141 = 31450562

Showing the first eight; more decompositions exist.
