Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742136, here are decompositions:

3 + 8742133 = 8742136
59 + 8742077 = 8742136
149 + 8741987 = 8742136
269 + 8741867 = 8742136
383 + 8741753 = 8742136
449 + 8741687 = 8742136
677 + 8741459 = 8742136
743 + 8741393 = 8742136

Showing the first eight; more decompositions exist.
