Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721254, here are decompositions:

97 + 8721157 = 8721254
193 + 8721061 = 8721254
211 + 8721043 = 8721254
277 + 8720977 = 8721254
307 + 8720947 = 8721254
313 + 8720941 = 8721254
457 + 8720797 = 8721254
541 + 8720713 = 8721254

Showing the first eight; more decompositions exist.
