Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642504, here are decompositions:

37 + 8642467 = 8642504
223 + 8642281 = 8642504
307 + 8642197 = 8642504
331 + 8642173 = 8642504
397 + 8642107 = 8642504
547 + 8641957 = 8642504
613 + 8641891 = 8642504
631 + 8641873 = 8642504

Showing the first eight; more decompositions exist.
