Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737420, here are decompositions:

47 + 8737373 = 8737420
71 + 8737349 = 8737420
149 + 8737271 = 8737420
173 + 8737247 = 8737420
227 + 8737193 = 8737420
281 + 8737139 = 8737420
347 + 8737073 = 8737420
353 + 8737067 = 8737420

Showing the first eight; more decompositions exist.
