Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742272, here are decompositions:

13 + 8742259 = 8742272
79 + 8742193 = 8742272
103 + 8742169 = 8742272
139 + 8742133 = 8742272
151 + 8742121 = 8742272
283 + 8741989 = 8742272
349 + 8741923 = 8742272
433 + 8741839 = 8742272

Showing the first eight; more decompositions exist.
