Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626908, here are decompositions:

67 + 31626841 = 31626908
199 + 31626709 = 31626908
241 + 31626667 = 31626908
337 + 31626571 = 31626908
409 + 31626499 = 31626908
487 + 31626421 = 31626908
541 + 31626367 = 31626908
571 + 31626337 = 31626908

Showing the first eight; more decompositions exist.
