Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737742, here are decompositions:

43 + 8737699 = 8737742
73 + 8737669 = 8737742
151 + 8737591 = 8737742
199 + 8737543 = 8737742
241 + 8737501 = 8737742
283 + 8737459 = 8737742
499 + 8737243 = 8737742
613 + 8737129 = 8737742

Showing the first eight; more decompositions exist.
