Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8733642, here are decompositions:

23 + 8733619 = 8733642
101 + 8733541 = 8733642
131 + 8733511 = 8733642
163 + 8733479 = 8733642
179 + 8733463 = 8733642
223 + 8733419 = 8733642
241 + 8733401 = 8733642
251 + 8733391 = 8733642

Showing the first eight; more decompositions exist.
