Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540098, here are decompositions:

67 + 31540031 = 31540098
89 + 31540009 = 31540098
127 + 31539971 = 31540098
131 + 31539967 = 31540098
167 + 31539931 = 31540098
197 + 31539901 = 31540098
241 + 31539857 = 31540098
277 + 31539821 = 31540098

Showing the first eight; more decompositions exist.
