Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756538, here are decompositions:

5 + 8756533 = 8756538
19 + 8756519 = 8756538
29 + 8756509 = 8756538
31 + 8756507 = 8756538
67 + 8756471 = 8756538
79 + 8756459 = 8756538
97 + 8756441 = 8756538
101 + 8756437 = 8756538

Showing the first eight; more decompositions exist.
