Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742182, here are decompositions:

13 + 8742169 = 8742182
61 + 8742121 = 8742182
79 + 8742103 = 8742182
193 + 8741989 = 8742182
199 + 8741983 = 8742182
271 + 8741911 = 8742182
433 + 8741749 = 8742182
439 + 8741743 = 8742182

Showing the first eight; more decompositions exist.
