Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630740, here are decompositions:

3 + 8630737 = 8630740
71 + 8630669 = 8630740
101 + 8630639 = 8630740
149 + 8630591 = 8630740
257 + 8630483 = 8630740
263 + 8630477 = 8630740
353 + 8630387 = 8630740
449 + 8630291 = 8630740

Showing the first eight; more decompositions exist.
