Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701972, here are decompositions:

11 + 8701961 = 8701972
23 + 8701949 = 8701972
89 + 8701883 = 8701972
101 + 8701871 = 8701972
263 + 8701709 = 8701972
269 + 8701703 = 8701972
401 + 8701571 = 8701972
443 + 8701529 = 8701972

Showing the first eight; more decompositions exist.
