Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730242, here are decompositions:

13 + 8730229 = 8730242
61 + 8730181 = 8730242
139 + 8730103 = 8730242
151 + 8730091 = 8730242
193 + 8730049 = 8730242
229 + 8730013 = 8730242
373 + 8729869 = 8730242
421 + 8729821 = 8730242

Showing the first eight; more decompositions exist.
