Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620972, here are decompositions:

23 + 8620949 = 8620972
29 + 8620943 = 8620972
131 + 8620841 = 8620972
233 + 8620739 = 8620972
251 + 8620721 = 8620972
281 + 8620691 = 8620972
383 + 8620589 = 8620972
401 + 8620571 = 8620972

Showing the first eight; more decompositions exist.
