Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705864, here are decompositions:

3 + 8705861 = 8705864
61 + 8705803 = 8705864
73 + 8705791 = 8705864
313 + 8705551 = 8705864
337 + 8705527 = 8705864
373 + 8705491 = 8705864
397 + 8705467 = 8705864
421 + 8705443 = 8705864

Showing the first eight; more decompositions exist.
