Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742084, here are decompositions:

7 + 8742077 = 8742084
17 + 8742067 = 8742084
47 + 8742037 = 8742084
73 + 8742011 = 8742084
97 + 8741987 = 8742084
101 + 8741983 = 8742084
107 + 8741977 = 8742084
137 + 8741947 = 8742084

Showing the first eight; more decompositions exist.
