Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700650, here are decompositions:

61 + 8700589 = 8700650
103 + 8700547 = 8700650
139 + 8700511 = 8700650
193 + 8700457 = 8700650
229 + 8700421 = 8700650
367 + 8700283 = 8700650
397 + 8700253 = 8700650
457 + 8700193 = 8700650

Showing the first eight; more decompositions exist.
