Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732378, here are decompositions:

7 + 8732371 = 8732378
79 + 8732299 = 8732378
139 + 8732239 = 8732378
181 + 8732197 = 8732378
241 + 8732137 = 8732378
307 + 8732071 = 8732378
331 + 8732047 = 8732378
349 + 8732029 = 8732378

Showing the first eight; more decompositions exist.
