Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710520, here are decompositions:

37 + 8710483 = 8710520
61 + 8710459 = 8710520
79 + 8710441 = 8710520
97 + 8710423 = 8710520
127 + 8710393 = 8710520
163 + 8710357 = 8710520
241 + 8710279 = 8710520
271 + 8710249 = 8710520

Showing the first eight; more decompositions exist.
