Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739564, here are decompositions:

61 + 8739503 = 8739564
73 + 8739491 = 8739564
83 + 8739481 = 8739564
101 + 8739463 = 8739564
131 + 8739433 = 8739564
167 + 8739397 = 8739564
173 + 8739391 = 8739564
227 + 8739337 = 8739564

Showing the first eight; more decompositions exist.
