Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701838, here are decompositions:

97 + 8701741 = 8701838
109 + 8701729 = 8701838
181 + 8701657 = 8701838
307 + 8701531 = 8701838
331 + 8701507 = 8701838
349 + 8701489 = 8701838
571 + 8701267 = 8701838
631 + 8701207 = 8701838

Showing the first eight; more decompositions exist.
