Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709172, here are decompositions:

23 + 8709149 = 8709172
113 + 8709059 = 8709172
431 + 8708741 = 8709172
509 + 8708663 = 8709172
653 + 8708519 = 8709172
743 + 8708429 = 8709172
761 + 8708411 = 8709172
881 + 8708291 = 8709172

Showing the first eight; more decompositions exist.
