Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637692, here are decompositions:

73 + 8637619 = 8637692
199 + 8637493 = 8637692
211 + 8637481 = 8637692
241 + 8637451 = 8637692
313 + 8637379 = 8637692
373 + 8637319 = 8637692
439 + 8637253 = 8637692
541 + 8637151 = 8637692

Showing the first eight; more decompositions exist.
