Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732438, here are decompositions:

7 + 8732431 = 8732438
67 + 8732371 = 8732438
139 + 8732299 = 8732438
181 + 8732257 = 8732438
199 + 8732239 = 8732438
229 + 8732209 = 8732438
241 + 8732197 = 8732438
367 + 8732071 = 8732438

Showing the first eight; more decompositions exist.
