Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660072, here are decompositions:

19 + 8660053 = 8660072
73 + 8659999 = 8660072
151 + 8659921 = 8660072
163 + 8659909 = 8660072
199 + 8659873 = 8660072
331 + 8659741 = 8660072
409 + 8659663 = 8660072
541 + 8659531 = 8660072

Showing the first eight; more decompositions exist.
