Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742226, here are decompositions:

29 + 8742197 = 8742226
149 + 8742077 = 8742226
167 + 8742059 = 8742226
239 + 8741987 = 8742226
293 + 8741933 = 8742226
359 + 8741867 = 8742226
587 + 8741639 = 8742226
617 + 8741609 = 8742226

Showing the first eight; more decompositions exist.
