Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730840, here are decompositions:

37 + 8730803 = 8730840
43 + 8730797 = 8730840
47 + 8730793 = 8730840
59 + 8730781 = 8730840
103 + 8730737 = 8730840
149 + 8730691 = 8730840
179 + 8730661 = 8730840
191 + 8730649 = 8730840

Showing the first eight; more decompositions exist.
