Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742538, here are decompositions:

41 + 8742497 = 8742538
89 + 8742449 = 8742538
137 + 8742401 = 8742538
179 + 8742359 = 8742538
191 + 8742347 = 8742538
461 + 8742077 = 8742538
479 + 8742059 = 8742538
587 + 8741951 = 8742538

Showing the first eight; more decompositions exist.
