Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642078, here are decompositions:

19 + 8642059 = 8642078
271 + 8641807 = 8642078
331 + 8641747 = 8642078
337 + 8641741 = 8642078
409 + 8641669 = 8642078
457 + 8641621 = 8642078
607 + 8641471 = 8642078
727 + 8641351 = 8642078

Showing the first eight; more decompositions exist.
