Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742244, here are decompositions:

47 + 8742197 = 8742244
83 + 8742161 = 8742244
167 + 8742077 = 8742244
233 + 8742011 = 8742244
257 + 8741987 = 8742244
293 + 8741951 = 8742244
311 + 8741933 = 8742244
383 + 8741861 = 8742244

Showing the first eight; more decompositions exist.
