Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604668, here are decompositions:

41 + 31604627 = 31604668
59 + 31604609 = 31604668
107 + 31604561 = 31604668
167 + 31604501 = 31604668
281 + 31604387 = 31604668
311 + 31604357 = 31604668
449 + 31604219 = 31604668
479 + 31604189 = 31604668

Showing the first eight; more decompositions exist.
