Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720060, here are decompositions:

3 + 8720057 = 8720060
61 + 8719999 = 8720060
73 + 8719987 = 8720060
109 + 8719951 = 8720060
157 + 8719903 = 8720060
229 + 8719831 = 8720060
241 + 8719819 = 8720060
313 + 8719747 = 8720060

Showing the first eight; more decompositions exist.
