Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452922, here are decompositions:

71 + 31452851 = 31452922
173 + 31452749 = 31452922
191 + 31452731 = 31452922
239 + 31452683 = 31452922
383 + 31452539 = 31452922
401 + 31452521 = 31452922
461 + 31452461 = 31452922
503 + 31452419 = 31452922

Showing the first eight; more decompositions exist.
