Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742774, here are decompositions:

97 + 8742677 = 8742774
101 + 8742673 = 8742774
137 + 8742637 = 8742774
151 + 8742623 = 8742774
197 + 8742577 = 8742774
223 + 8742551 = 8742774
233 + 8742541 = 8742774
263 + 8742511 = 8742774

Showing the first eight; more decompositions exist.
