Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697238, here are decompositions:

5 + 8697233 = 8697238
131 + 8697107 = 8697238
149 + 8697089 = 8697238
239 + 8696999 = 8697238
401 + 8696837 = 8697238
449 + 8696789 = 8697238
479 + 8696759 = 8697238
587 + 8696651 = 8697238

Showing the first eight; more decompositions exist.
