Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453070, here are decompositions:

31 + 31453039 = 31453070
97 + 31452973 = 31453070
127 + 31452943 = 31453070
211 + 31452859 = 31453070
241 + 31452829 = 31453070
277 + 31452793 = 31453070
307 + 31452763 = 31453070
331 + 31452739 = 31453070

Showing the first eight; more decompositions exist.
