Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543640, here are decompositions:

101 + 33543539 = 33543640
131 + 33543509 = 33543640
281 + 33543359 = 33543640
353 + 33543287 = 33543640
401 + 33543239 = 33543640
467 + 33543173 = 33543640
479 + 33543161 = 33543640
491 + 33543149 = 33543640

Showing the first eight; more decompositions exist.
