Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730780, here are decompositions:

43 + 8730737 = 8730780
83 + 8730697 = 8730780
89 + 8730691 = 8730780
131 + 8730649 = 8730780
151 + 8730629 = 8730780
173 + 8730607 = 8730780
197 + 8730583 = 8730780
251 + 8730529 = 8730780

Showing the first eight; more decompositions exist.
