Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664238, here are decompositions:

131 + 8664107 = 8664238
251 + 8663987 = 8664238
269 + 8663969 = 8664238
419 + 8663819 = 8664238
431 + 8663807 = 8664238
461 + 8663777 = 8664238
617 + 8663621 = 8664238
659 + 8663579 = 8664238

Showing the first eight; more decompositions exist.
