Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452826, here are decompositions:

23 + 31452803 = 31452826
107 + 31452719 = 31452826
149 + 31452677 = 31452826
227 + 31452599 = 31452826
239 + 31452587 = 31452826
593 + 31452233 = 31452826
617 + 31452209 = 31452826
653 + 31452173 = 31452826

Showing the first eight; more decompositions exist.
