Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993638, here are decompositions:

97 + 993541 = 993638
157 + 993481 = 993638
241 + 993397 = 993638
271 + 993367 = 993638
397 + 993241 = 993638
421 + 993217 = 993638
439 + 993199 = 993638
601 + 993037 = 993638

Showing the first eight; more decompositions exist.
