Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455692, here are decompositions:

43 + 31455649 = 31455692
61 + 31455631 = 31455692
193 + 31455499 = 31455692
283 + 31455409 = 31455692
379 + 31455313 = 31455692
421 + 31455271 = 31455692
571 + 31455121 = 31455692
661 + 31455031 = 31455692

Showing the first eight; more decompositions exist.
