Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468028, here are decompositions:

61 + 31467967 = 31468028
79 + 31467949 = 31468028
181 + 31467847 = 31468028
199 + 31467829 = 31468028
307 + 31467721 = 31468028
337 + 31467691 = 31468028
439 + 31467589 = 31468028
457 + 31467571 = 31468028

Showing the first eight; more decompositions exist.
