Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691698, here are decompositions:

31 + 8691667 = 8691698
109 + 8691589 = 8691698
157 + 8691541 = 8691698
229 + 8691469 = 8691698
307 + 8691391 = 8691698
331 + 8691367 = 8691698
487 + 8691211 = 8691698
541 + 8691157 = 8691698

Showing the first eight; more decompositions exist.
