Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742118, here are decompositions:

41 + 8742077 = 8742118
59 + 8742059 = 8742118
107 + 8742011 = 8742118
131 + 8741987 = 8742118
167 + 8741951 = 8742118
251 + 8741867 = 8742118
257 + 8741861 = 8742118
317 + 8741801 = 8742118

Showing the first eight; more decompositions exist.
