Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499726, here are decompositions:

67 + 31499659 = 31499726
127 + 31499599 = 31499726
229 + 31499497 = 31499726
397 + 31499329 = 31499726
487 + 31499239 = 31499726
499 + 31499227 = 31499726
619 + 31499107 = 31499726
733 + 31498993 = 31499726

Showing the first eight; more decompositions exist.
