Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739860, here are decompositions:

37 + 8739823 = 8739860
139 + 8739721 = 8739860
193 + 8739667 = 8739860
223 + 8739637 = 8739860
277 + 8739583 = 8739860
331 + 8739529 = 8739860
379 + 8739481 = 8739860
397 + 8739463 = 8739860

Showing the first eight; more decompositions exist.
