Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468052, here are decompositions:

103 + 31467949 = 31468052
199 + 31467853 = 31468052
223 + 31467829 = 31468052
241 + 31467811 = 31468052
331 + 31467721 = 31468052
463 + 31467589 = 31468052
571 + 31467481 = 31468052
619 + 31467433 = 31468052

Showing the first eight; more decompositions exist.
