Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708072, here are decompositions:

3 + 8708069 = 8708072
73 + 8707999 = 8708072
103 + 8707969 = 8708072
193 + 8707879 = 8708072
199 + 8707873 = 8708072
211 + 8707861 = 8708072
229 + 8707843 = 8708072
421 + 8707651 = 8708072

Showing the first eight; more decompositions exist.
