Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540064, here are decompositions:

97 + 31539967 = 31540064
163 + 31539901 = 31540064
307 + 31539757 = 31540064
337 + 31539727 = 31540064
421 + 31539643 = 31540064
541 + 31539523 = 31540064
643 + 31539421 = 31540064
727 + 31539337 = 31540064

Showing the first eight; more decompositions exist.
