Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492034, here are decompositions:

3 + 31492031 = 31492034
193 + 31491841 = 31492034
241 + 31491793 = 31492034
307 + 31491727 = 31492034
337 + 31491697 = 31492034
373 + 31491661 = 31492034
397 + 31491637 = 31492034
421 + 31491613 = 31492034

Showing the first eight; more decompositions exist.
