Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739542, here are decompositions:

13 + 8739529 = 8739542
43 + 8739499 = 8739542
61 + 8739481 = 8739542
79 + 8739463 = 8739542
109 + 8739433 = 8739542
151 + 8739391 = 8739542
193 + 8739349 = 8739542
211 + 8739331 = 8739542

Showing the first eight; more decompositions exist.
