Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742124, here are decompositions:

3 + 8742121 = 8742124
47 + 8742077 = 8742124
113 + 8742011 = 8742124
137 + 8741987 = 8742124
173 + 8741951 = 8742124
191 + 8741933 = 8742124
257 + 8741867 = 8742124
263 + 8741861 = 8742124

Showing the first eight; more decompositions exist.
