Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660242, here are decompositions:

53 + 8660189 = 8660242
191 + 8660051 = 8660242
293 + 8659949 = 8660242
431 + 8659811 = 8660242
449 + 8659793 = 8660242
599 + 8659643 = 8660242
641 + 8659601 = 8660242
653 + 8659589 = 8660242

Showing the first eight; more decompositions exist.
