Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452692, here are decompositions:

43 + 31452649 = 31452692
109 + 31452583 = 31452692
163 + 31452529 = 31452692
199 + 31452493 = 31452692
211 + 31452481 = 31452692
241 + 31452451 = 31452692
409 + 31452283 = 31452692
571 + 31452121 = 31452692

Showing the first eight; more decompositions exist.
