Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660144, here are decompositions:

37 + 8660107 = 8660144
67 + 8660077 = 8660144
223 + 8659921 = 8660144
271 + 8659873 = 8660144
277 + 8659867 = 8660144
307 + 8659837 = 8660144
397 + 8659747 = 8660144
433 + 8659711 = 8660144

Showing the first eight; more decompositions exist.
