Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697490, here are decompositions:

83 + 8697407 = 8697490
101 + 8697389 = 8697490
227 + 8697263 = 8697490
251 + 8697239 = 8697490
257 + 8697233 = 8697490
383 + 8697107 = 8697490
401 + 8697089 = 8697490
491 + 8696999 = 8697490

Showing the first eight; more decompositions exist.
