Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468328, here are decompositions:

97 + 31468231 = 31468328
127 + 31468201 = 31468328
181 + 31468147 = 31468328
379 + 31467949 = 31468328
499 + 31467829 = 31468328
601 + 31467727 = 31468328
607 + 31467721 = 31468328
739 + 31467589 = 31468328

Showing the first eight; more decompositions exist.
