Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642482, here are decompositions:

29 + 8642453 = 8642482
53 + 8642429 = 8642482
179 + 8642303 = 8642482
293 + 8642189 = 8642482
383 + 8642099 = 8642482
419 + 8642063 = 8642482
449 + 8642033 = 8642482
479 + 8642003 = 8642482

Showing the first eight; more decompositions exist.
