Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739286, here are decompositions:

5 + 8739281 = 8739286
89 + 8739197 = 8739286
167 + 8739119 = 8739286
173 + 8739113 = 8739286
233 + 8739053 = 8739286
263 + 8739023 = 8739286
443 + 8738843 = 8739286
449 + 8738837 = 8739286

Showing the first eight; more decompositions exist.
