Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641948, here are decompositions:

131 + 8641817 = 8641948
167 + 8641781 = 8641948
239 + 8641709 = 8641948
251 + 8641697 = 8641948
317 + 8641631 = 8641948
401 + 8641547 = 8641948
431 + 8641517 = 8641948
479 + 8641469 = 8641948

Showing the first eight; more decompositions exist.
