Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499704, here are decompositions:

83 + 31499621 = 31499704
167 + 31499537 = 31499704
293 + 31499411 = 31499704
317 + 31499387 = 31499704
521 + 31499183 = 31499704
641 + 31499063 = 31499704
647 + 31499057 = 31499704
683 + 31499021 = 31499704

Showing the first eight; more decompositions exist.
