Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730488, here are decompositions:

139 + 8730349 = 8730488
157 + 8730331 = 8730488
181 + 8730307 = 8730488
307 + 8730181 = 8730488
331 + 8730157 = 8730488
337 + 8730151 = 8730488
397 + 8730091 = 8730488
421 + 8730067 = 8730488

Showing the first eight; more decompositions exist.
