Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36638, here are decompositions:

31 + 36607 = 36638
67 + 36571 = 36638
79 + 36559 = 36638
97 + 36541 = 36638
109 + 36529 = 36638
181 + 36457 = 36638
331 + 36307 = 36638
397 + 36241 = 36638

Showing the first eight; more decompositions exist.
