Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731078, here are decompositions:

47 + 8731031 = 8731078
101 + 8730977 = 8731078
131 + 8730947 = 8731078
149 + 8730929 = 8731078
197 + 8730881 = 8731078
227 + 8730851 = 8731078
281 + 8730797 = 8731078
449 + 8730629 = 8731078

Showing the first eight; more decompositions exist.
