Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742082, here are decompositions:

5 + 8742077 = 8742082
23 + 8742059 = 8742082
71 + 8742011 = 8742082
131 + 8741951 = 8742082
149 + 8741933 = 8742082
269 + 8741813 = 8742082
281 + 8741801 = 8742082
383 + 8741699 = 8742082

Showing the first eight; more decompositions exist.
