Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730398, here are decompositions:

67 + 8730331 = 8730398
241 + 8730157 = 8730398
307 + 8730091 = 8730398
331 + 8730067 = 8730398
349 + 8730049 = 8730398
421 + 8729977 = 8730398
577 + 8729821 = 8730398
631 + 8729767 = 8730398

Showing the first eight; more decompositions exist.
