Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458792, here are decompositions:

5 + 31458787 = 31458792
31 + 31458761 = 31458792
73 + 31458719 = 31458792
83 + 31458709 = 31458792
89 + 31458703 = 31458792
103 + 31458689 = 31458792
149 + 31458643 = 31458792
191 + 31458601 = 31458792

Showing the first eight; more decompositions exist.
