Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730378, here are decompositions:

29 + 8730349 = 8730378
37 + 8730341 = 8730378
47 + 8730331 = 8730378
67 + 8730311 = 8730378
71 + 8730307 = 8730378
109 + 8730269 = 8730378
149 + 8730229 = 8730378
197 + 8730181 = 8730378

Showing the first eight; more decompositions exist.
