Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542668, here are decompositions:

37 + 31542631 = 31542668
109 + 31542559 = 31542668
181 + 31542487 = 31542668
211 + 31542457 = 31542668
229 + 31542439 = 31542668
271 + 31542397 = 31542668
277 + 31542391 = 31542668
439 + 31542229 = 31542668

Showing the first eight; more decompositions exist.
