Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742126, here are decompositions:

5 + 8742121 = 8742126
23 + 8742103 = 8742126
59 + 8742067 = 8742126
67 + 8742059 = 8742126
89 + 8742037 = 8742126
137 + 8741989 = 8742126
139 + 8741987 = 8742126
149 + 8741977 = 8742126

Showing the first eight; more decompositions exist.
