Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649992, here are decompositions:

19 + 8649973 = 8649992
139 + 8649853 = 8649992
199 + 8649793 = 8649992
229 + 8649763 = 8649992
271 + 8649721 = 8649992
331 + 8649661 = 8649992
523 + 8649469 = 8649992
541 + 8649451 = 8649992

Showing the first eight; more decompositions exist.
