Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742436, here are decompositions:

83 + 8742353 = 8742436
89 + 8742347 = 8742436
173 + 8742263 = 8742436
239 + 8742197 = 8742436
359 + 8742077 = 8742436
449 + 8741987 = 8742436
503 + 8741933 = 8742436
569 + 8741867 = 8742436

Showing the first eight; more decompositions exist.
