Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647542, here are decompositions:

5 + 8647537 = 8647542
11 + 8647531 = 8647542
31 + 8647511 = 8647542
41 + 8647501 = 8647542
73 + 8647469 = 8647542
83 + 8647459 = 8647542
131 + 8647411 = 8647542
149 + 8647393 = 8647542

Showing the first eight; more decompositions exist.
