Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750438, here are decompositions:

61 + 8750377 = 8750438
97 + 8750341 = 8750438
199 + 8750239 = 8750438
211 + 8750227 = 8750438
241 + 8750197 = 8750438
331 + 8750107 = 8750438
337 + 8750101 = 8750438
421 + 8750017 = 8750438

Showing the first eight; more decompositions exist.
