Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709100, here are decompositions:

41 + 8709059 = 8709100
131 + 8708969 = 8709100
137 + 8708963 = 8709100
251 + 8708849 = 8709100
269 + 8708831 = 8709100
293 + 8708807 = 8709100
359 + 8708741 = 8709100
383 + 8708717 = 8709100

Showing the first eight; more decompositions exist.
