Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540094, here are decompositions:

31 + 31540063 = 31540094
127 + 31539967 = 31540094
163 + 31539931 = 31540094
193 + 31539901 = 31540094
277 + 31539817 = 31540094
331 + 31539763 = 31540094
337 + 31539757 = 31540094
367 + 31539727 = 31540094

Showing the first eight; more decompositions exist.
