Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708830, here are decompositions:

23 + 8708807 = 8708830
89 + 8708741 = 8708830
113 + 8708717 = 8708830
167 + 8708663 = 8708830
173 + 8708657 = 8708830
191 + 8708639 = 8708830
239 + 8708591 = 8708830
293 + 8708537 = 8708830

Showing the first eight; more decompositions exist.
