Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709154, here are decompositions:

5 + 8709149 = 8709154
191 + 8708963 = 8709154
347 + 8708807 = 8709154
491 + 8708663 = 8709154
563 + 8708591 = 8709154
617 + 8708537 = 8709154
647 + 8708507 = 8709154
653 + 8708501 = 8709154

Showing the first eight; more decompositions exist.
