Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724206, here are decompositions:

37 + 8724169 = 8724206
67 + 8724139 = 8724206
79 + 8724127 = 8724206
193 + 8724013 = 8724206
229 + 8723977 = 8724206
277 + 8723929 = 8724206
307 + 8723899 = 8724206
313 + 8723893 = 8724206

Showing the first eight; more decompositions exist.
