Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642290, here are decompositions:

53 + 8642237 = 8642290
101 + 8642189 = 8642290
131 + 8642159 = 8642290
149 + 8642141 = 8642290
179 + 8642111 = 8642290
191 + 8642099 = 8642290
227 + 8642063 = 8642290
233 + 8642057 = 8642290

Showing the first eight; more decompositions exist.
