Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742026, here are decompositions:

37 + 8741989 = 8742026
43 + 8741983 = 8742026
79 + 8741947 = 8742026
103 + 8741923 = 8742026
229 + 8741797 = 8742026
277 + 8741749 = 8742026
283 + 8741743 = 8742026
463 + 8741563 = 8742026

Showing the first eight; more decompositions exist.
