Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450550, here are decompositions:

7 + 31450543 = 31450550
67 + 31450483 = 31450550
127 + 31450423 = 31450550
139 + 31450411 = 31450550
163 + 31450387 = 31450550
181 + 31450369 = 31450550
199 + 31450351 = 31450550
331 + 31450219 = 31450550

Showing the first eight; more decompositions exist.
