Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742250, here are decompositions:

53 + 8742197 = 8742250
89 + 8742161 = 8742250
173 + 8742077 = 8742250
191 + 8742059 = 8742250
239 + 8742011 = 8742250
263 + 8741987 = 8742250
317 + 8741933 = 8742250
383 + 8741867 = 8742250

Showing the first eight; more decompositions exist.
