Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 965840, here are decompositions:

61 + 965779 = 965840
67 + 965773 = 965840
163 + 965677 = 965840
181 + 965659 = 965840
193 + 965647 = 965840
229 + 965611 = 965840
307 + 965533 = 965840
349 + 965491 = 965840

Showing the first eight; more decompositions exist.
