Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8657924, here are decompositions:

43 + 8657881 = 8657924
73 + 8657851 = 8657924
97 + 8657827 = 8657924
157 + 8657767 = 8657924
193 + 8657731 = 8657924
313 + 8657611 = 8657924
367 + 8657557 = 8657924
421 + 8657503 = 8657924

Showing the first eight; more decompositions exist.
