Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458764, here are decompositions:

3 + 31458761 = 31458764
61 + 31458703 = 31458764
67 + 31458697 = 31458764
97 + 31458667 = 31458764
157 + 31458607 = 31458764
163 + 31458601 = 31458764
223 + 31458541 = 31458764
277 + 31458487 = 31458764

Showing the first eight; more decompositions exist.
