Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742992, here are decompositions:

19 + 8742973 = 8742992
61 + 8742931 = 8742992
73 + 8742919 = 8742992
421 + 8742571 = 8742992
463 + 8742529 = 8742992
499 + 8742493 = 8742992
523 + 8742469 = 8742992
571 + 8742421 = 8742992

Showing the first eight; more decompositions exist.
