Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697742, here are decompositions:

59 + 8697683 = 8697742
101 + 8697641 = 8697742
191 + 8697551 = 8697742
233 + 8697509 = 8697742
239 + 8697503 = 8697742
353 + 8697389 = 8697742
479 + 8697263 = 8697742
503 + 8697239 = 8697742

Showing the first eight; more decompositions exist.
