Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742044, here are decompositions:

7 + 8742037 = 8742044
61 + 8741983 = 8742044
67 + 8741977 = 8742044
97 + 8741947 = 8742044
523 + 8741521 = 8742044
541 + 8741503 = 8742044
607 + 8741437 = 8742044
613 + 8741431 = 8742044

Showing the first eight; more decompositions exist.
