Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691238, here are decompositions:

29 + 8691209 = 8691238
71 + 8691167 = 8691238
137 + 8691101 = 8691238
317 + 8690921 = 8691238
449 + 8690789 = 8691238
599 + 8690639 = 8691238
761 + 8690477 = 8691238
827 + 8690411 = 8691238

Showing the first eight; more decompositions exist.
