Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730340, here are decompositions:

29 + 8730311 = 8730340
53 + 8730287 = 8730340
71 + 8730269 = 8730340
83 + 8730257 = 8730340
191 + 8730149 = 8730340
257 + 8730083 = 8730340
263 + 8730077 = 8730340
401 + 8729939 = 8730340

Showing the first eight; more decompositions exist.
