Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742650, here are decompositions:

13 + 8742637 = 8742650
73 + 8742577 = 8742650
79 + 8742571 = 8742650
109 + 8742541 = 8742650
139 + 8742511 = 8742650
151 + 8742499 = 8742650
157 + 8742493 = 8742650
181 + 8742469 = 8742650

Showing the first eight; more decompositions exist.
