Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742002, here are decompositions:

13 + 8741989 = 8742002
19 + 8741983 = 8742002
79 + 8741923 = 8742002
163 + 8741839 = 8742002
223 + 8741779 = 8742002
439 + 8741563 = 8742002
499 + 8741503 = 8742002
523 + 8741479 = 8742002

Showing the first eight; more decompositions exist.
