Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732668, here are decompositions:

29 + 8732639 = 8732668
41 + 8732627 = 8732668
167 + 8732501 = 8732668
179 + 8732489 = 8732668
239 + 8732429 = 8732668
251 + 8732417 = 8732668
257 + 8732411 = 8732668
317 + 8732351 = 8732668

Showing the first eight; more decompositions exist.
