Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708782, here are decompositions:

41 + 8708741 = 8708782
191 + 8708591 = 8708782
263 + 8708519 = 8708782
281 + 8708501 = 8708782
353 + 8708429 = 8708782
359 + 8708423 = 8708782
389 + 8708393 = 8708782
443 + 8708339 = 8708782

Showing the first eight; more decompositions exist.
