Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12910, here are decompositions:

3 + 12907 = 12910
11 + 12899 = 12910
17 + 12893 = 12910
89 + 12821 = 12910
101 + 12809 = 12910
167 + 12743 = 12910
197 + 12713 = 12910
239 + 12671 = 12910

Showing the first eight; more decompositions exist.
