Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742646, here are decompositions:

23 + 8742623 = 8742646
149 + 8742497 = 8742646
197 + 8742449 = 8742646
293 + 8742353 = 8742646
383 + 8742263 = 8742646
449 + 8742197 = 8742646
569 + 8742077 = 8742646
587 + 8742059 = 8742646

Showing the first eight; more decompositions exist.
