Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742590, here are decompositions:

13 + 8742577 = 8742590
19 + 8742571 = 8742590
61 + 8742529 = 8742590
79 + 8742511 = 8742590
97 + 8742493 = 8742590
127 + 8742463 = 8742590
211 + 8742379 = 8742590
223 + 8742367 = 8742590

Showing the first eight; more decompositions exist.
