Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707290, here are decompositions:

13 + 8707277 = 8707290
17 + 8707273 = 8707290
71 + 8707219 = 8707290
83 + 8707207 = 8707290
101 + 8707189 = 8707290
107 + 8707183 = 8707290
131 + 8707159 = 8707290
167 + 8707123 = 8707290

Showing the first eight; more decompositions exist.
