Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690210, here are decompositions:

7 + 8690203 = 8690210
19 + 8690191 = 8690210
37 + 8690173 = 8690210
223 + 8689987 = 8690210
229 + 8689981 = 8690210
241 + 8689969 = 8690210
367 + 8689843 = 8690210
433 + 8689777 = 8690210

Showing the first eight; more decompositions exist.
