Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742112, here are decompositions:

53 + 8742059 = 8742112
101 + 8742011 = 8742112
179 + 8741933 = 8742112
251 + 8741861 = 8742112
311 + 8741801 = 8742112
359 + 8741753 = 8742112
503 + 8741609 = 8742112
641 + 8741471 = 8742112

Showing the first eight; more decompositions exist.
