Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637112, here are decompositions:

5 + 8637107 = 8637112
53 + 8637059 = 8637112
59 + 8637053 = 8637112
191 + 8636921 = 8637112
293 + 8636819 = 8637112
311 + 8636801 = 8637112
353 + 8636759 = 8637112
479 + 8636633 = 8637112

Showing the first eight; more decompositions exist.
