Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725922, here are decompositions:

109 + 8725813 = 8725922
223 + 8725699 = 8725922
241 + 8725681 = 8725922
313 + 8725609 = 8725922
433 + 8725489 = 8725922
463 + 8725459 = 8725922
523 + 8725399 = 8725922
643 + 8725279 = 8725922

Showing the first eight; more decompositions exist.
