Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642498, here are decompositions:

31 + 8642467 = 8642498
379 + 8642119 = 8642498
421 + 8642077 = 8642498
439 + 8642059 = 8642498
541 + 8641957 = 8642498
607 + 8641891 = 8642498
691 + 8641807 = 8642498
751 + 8641747 = 8642498

Showing the first eight; more decompositions exist.
