Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736820, here are decompositions:

3 + 8736817 = 8736820
11 + 8736809 = 8736820
101 + 8736719 = 8736820
137 + 8736683 = 8736820
167 + 8736653 = 8736820
173 + 8736647 = 8736820
227 + 8736593 = 8736820
311 + 8736509 = 8736820

Showing the first eight; more decompositions exist.
