Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742566, here are decompositions:

37 + 8742529 = 8742566
67 + 8742499 = 8742566
73 + 8742493 = 8742566
97 + 8742469 = 8742566
103 + 8742463 = 8742566
199 + 8742367 = 8742566
307 + 8742259 = 8742566
373 + 8742193 = 8742566

Showing the first eight; more decompositions exist.
