Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742662, here are decompositions:

151 + 8742511 = 8742662
163 + 8742499 = 8742662
193 + 8742469 = 8742662
199 + 8742463 = 8742662
241 + 8742421 = 8742662
283 + 8742379 = 8742662
349 + 8742313 = 8742662
541 + 8742121 = 8742662

Showing the first eight; more decompositions exist.
