Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8713072, here are decompositions:

3 + 8713069 = 8713072
29 + 8713043 = 8713072
59 + 8713013 = 8713072
293 + 8712779 = 8713072
311 + 8712761 = 8713072
359 + 8712713 = 8713072
443 + 8712629 = 8713072
461 + 8712611 = 8713072

Showing the first eight; more decompositions exist.
