Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750020, here are decompositions:

3 + 8750017 = 8750020
29 + 8749991 = 8750020
173 + 8749847 = 8750020
179 + 8749841 = 8750020
233 + 8749787 = 8750020
269 + 8749751 = 8750020
431 + 8749589 = 8750020
449 + 8749571 = 8750020

Showing the first eight; more decompositions exist.
