Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730978, here are decompositions:

29 + 8730949 = 8730978
31 + 8730947 = 8730978
59 + 8730919 = 8730978
89 + 8730889 = 8730978
97 + 8730881 = 8730978
127 + 8730851 = 8730978
131 + 8730847 = 8730978
181 + 8730797 = 8730978

Showing the first eight; more decompositions exist.
