Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452622, here are decompositions:

23 + 31452599 = 31452622
83 + 31452539 = 31452622
101 + 31452521 = 31452622
281 + 31452341 = 31452622
389 + 31452233 = 31452622
419 + 31452203 = 31452622
449 + 31452173 = 31452622
491 + 31452131 = 31452622

Showing the first eight; more decompositions exist.
