Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755642, here are decompositions:

3 + 8755639 = 8755642
23 + 8755619 = 8755642
29 + 8755613 = 8755642
41 + 8755601 = 8755642
83 + 8755559 = 8755642
113 + 8755529 = 8755642
173 + 8755469 = 8755642
191 + 8755451 = 8755642

Showing the first eight; more decompositions exist.
