Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721354, here are decompositions:

41 + 8721313 = 8721354
43 + 8721311 = 8721354
73 + 8721281 = 8721354
101 + 8721253 = 8721354
157 + 8721197 = 8721354
163 + 8721191 = 8721354
197 + 8721157 = 8721354
233 + 8721121 = 8721354

Showing the first eight; more decompositions exist.
