Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655770, here are decompositions:

31 + 8655739 = 8655770
37 + 8655733 = 8655770
139 + 8655631 = 8655770
313 + 8655457 = 8655770
337 + 8655433 = 8655770
349 + 8655421 = 8655770
367 + 8655403 = 8655770
421 + 8655349 = 8655770

Showing the first eight; more decompositions exist.
