Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730842, here are decompositions:

61 + 8730781 = 8730842
151 + 8730691 = 8730842
181 + 8730661 = 8730842
193 + 8730649 = 8730842
223 + 8730619 = 8730842
283 + 8730559 = 8730842
313 + 8730529 = 8730842
331 + 8730511 = 8730842

Showing the first eight; more decompositions exist.
