Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742248, here are decompositions:

61 + 8742187 = 8742248
79 + 8742169 = 8742248
127 + 8742121 = 8742248
181 + 8742067 = 8742248
211 + 8742037 = 8742248
271 + 8741977 = 8742248
337 + 8741911 = 8742248
409 + 8741839 = 8742248

Showing the first eight; more decompositions exist.
