Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73638, here are decompositions:

29 + 73609 = 73638
31 + 73607 = 73638
41 + 73597 = 73638
67 + 73571 = 73638
109 + 73529 = 73638
167 + 73471 = 73638
179 + 73459 = 73638
251 + 73387 = 73638

Showing the first eight; more decompositions exist.
