Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756742, here are decompositions:

53 + 8756689 = 8756742
73 + 8756669 = 8756742
83 + 8756659 = 8756742
89 + 8756653 = 8756742
109 + 8756633 = 8756742
149 + 8756593 = 8756742
151 + 8756591 = 8756742
191 + 8756551 = 8756742

Showing the first eight; more decompositions exist.
