Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731284, here are decompositions:

7 + 8731277 = 8731284
53 + 8731231 = 8731284
71 + 8731213 = 8731284
73 + 8731211 = 8731284
83 + 8731201 = 8731284
97 + 8731187 = 8731284
131 + 8731153 = 8731284
173 + 8731111 = 8731284

Showing the first eight; more decompositions exist.
