Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752072, here are decompositions:

5 + 8752067 = 8752072
41 + 8752031 = 8752072
233 + 8751839 = 8752072
269 + 8751803 = 8752072
401 + 8751671 = 8752072
443 + 8751629 = 8752072
479 + 8751593 = 8752072
509 + 8751563 = 8752072

Showing the first eight; more decompositions exist.
