Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648690, here are decompositions:

3 + 8648687 = 8648690
13 + 8648677 = 8648690
139 + 8648551 = 8648690
157 + 8648533 = 8648690
277 + 8648413 = 8648690
367 + 8648323 = 8648690
373 + 8648317 = 8648690
439 + 8648251 = 8648690

Showing the first eight; more decompositions exist.
