Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697142, here are decompositions:

29 + 8697113 = 8697142
53 + 8697089 = 8697142
149 + 8696993 = 8697142
191 + 8696951 = 8697142
239 + 8696903 = 8697142
353 + 8696789 = 8697142
383 + 8696759 = 8697142
431 + 8696711 = 8697142

Showing the first eight; more decompositions exist.
