Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468070, here are decompositions:

3 + 31468067 = 31468070
43 + 31468027 = 31468070
103 + 31467967 = 31468070
223 + 31467847 = 31468070
241 + 31467829 = 31468070
307 + 31467763 = 31468070
349 + 31467721 = 31468070
379 + 31467691 = 31468070

Showing the first eight; more decompositions exist.
