Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655142, here are decompositions:

71 + 8655071 = 8655142
101 + 8655041 = 8655142
113 + 8655029 = 8655142
131 + 8655011 = 8655142
269 + 8654873 = 8655142
383 + 8654759 = 8655142
389 + 8654753 = 8655142
479 + 8654663 = 8655142

Showing the first eight; more decompositions exist.
