Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731084, here are decompositions:

53 + 8731031 = 8731084
101 + 8730983 = 8731084
107 + 8730977 = 8731084
137 + 8730947 = 8731084
191 + 8730893 = 8731084
227 + 8730857 = 8731084
233 + 8730851 = 8731084
281 + 8730803 = 8731084

Showing the first eight; more decompositions exist.
