Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450422, here are decompositions:

11 + 31450411 = 31450422
13 + 31450409 = 31450422
53 + 31450369 = 31450422
71 + 31450351 = 31450422
109 + 31450313 = 31450422
131 + 31450291 = 31450422
151 + 31450271 = 31450422
281 + 31450141 = 31450422

Showing the first eight; more decompositions exist.
