Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730890, here are decompositions:

31 + 8730859 = 8730890
43 + 8730847 = 8730890
97 + 8730793 = 8730890
109 + 8730781 = 8730890
193 + 8730697 = 8730890
199 + 8730691 = 8730890
229 + 8730661 = 8730890
241 + 8730649 = 8730890

Showing the first eight; more decompositions exist.
