Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742104, here are decompositions:

37 + 8742067 = 8742104
67 + 8742037 = 8742104
127 + 8741977 = 8742104
157 + 8741947 = 8742104
181 + 8741923 = 8742104
193 + 8741911 = 8742104
307 + 8741797 = 8742104
421 + 8741683 = 8742104

Showing the first eight; more decompositions exist.
