Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730220, here are decompositions:

71 + 8730149 = 8730220
137 + 8730083 = 8730220
281 + 8729939 = 8730220
353 + 8729867 = 8730220
383 + 8729837 = 8730220
419 + 8729801 = 8730220
491 + 8729729 = 8730220
503 + 8729717 = 8730220

Showing the first eight; more decompositions exist.
