Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739388, here are decompositions:

29 + 8739359 = 8739388
89 + 8739299 = 8739388
107 + 8739281 = 8739388
179 + 8739209 = 8739388
191 + 8739197 = 8739388
269 + 8739119 = 8739388
431 + 8738957 = 8739388
587 + 8738801 = 8739388

Showing the first eight; more decompositions exist.
