Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725742, here are decompositions:

43 + 8725699 = 8725742
61 + 8725681 = 8725742
73 + 8725669 = 8725742
211 + 8725531 = 8725742
283 + 8725459 = 8725742
313 + 8725429 = 8725742
379 + 8725363 = 8725742
463 + 8725279 = 8725742

Showing the first eight; more decompositions exist.
