Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938624, here are decompositions:

7 + 938617 = 938624
13 + 938611 = 938624
61 + 938563 = 938624
277 + 938347 = 938624
283 + 938341 = 938624
331 + 938293 = 938624
367 + 938257 = 938624
373 + 938251 = 938624

Showing the first eight; more decompositions exist.
