Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742102, here are decompositions:

43 + 8742059 = 8742102
113 + 8741989 = 8742102
151 + 8741951 = 8742102
179 + 8741923 = 8742102
191 + 8741911 = 8742102
241 + 8741861 = 8742102
263 + 8741839 = 8742102
349 + 8741753 = 8742102

Showing the first eight; more decompositions exist.
