Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628374, here are decompositions:

103 + 8628271 = 8628374
193 + 8628181 = 8628374
277 + 8628097 = 8628374
367 + 8628007 = 8628374
397 + 8627977 = 8628374
421 + 8627953 = 8628374
463 + 8627911 = 8628374
523 + 8627851 = 8628374

Showing the first eight; more decompositions exist.
