Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580846, here are decompositions:

67 + 31580779 = 31580846
127 + 31580719 = 31580846
163 + 31580683 = 31580846
229 + 31580617 = 31580846
307 + 31580539 = 31580846
499 + 31580347 = 31580846
523 + 31580323 = 31580846
607 + 31580239 = 31580846

Showing the first eight; more decompositions exist.
