Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730258, here are decompositions:

29 + 8730229 = 8730258
101 + 8730157 = 8730258
107 + 8730151 = 8730258
109 + 8730149 = 8730258
167 + 8730091 = 8730258
181 + 8730077 = 8730258
191 + 8730067 = 8730258
281 + 8729977 = 8730258

Showing the first eight; more decompositions exist.
