Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672402, here are decompositions:

139 + 8672263 = 8672402
163 + 8672239 = 8672402
199 + 8672203 = 8672402
241 + 8672161 = 8672402
421 + 8671981 = 8672402
691 + 8671711 = 8672402
733 + 8671669 = 8672402
769 + 8671633 = 8672402

Showing the first eight; more decompositions exist.
