Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742770, here are decompositions:

31 + 8742739 = 8742770
97 + 8742673 = 8742770
193 + 8742577 = 8742770
199 + 8742571 = 8742770
229 + 8742541 = 8742770
241 + 8742529 = 8742770
271 + 8742499 = 8742770
277 + 8742493 = 8742770

Showing the first eight; more decompositions exist.
