Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730478, here are decompositions:

5 + 8730473 = 8730478
11 + 8730467 = 8730478
101 + 8730377 = 8730478
137 + 8730341 = 8730478
167 + 8730311 = 8730478
191 + 8730287 = 8730478
401 + 8730077 = 8730478
479 + 8729999 = 8730478

Showing the first eight; more decompositions exist.
