Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 129318, here are decompositions:

5 + 129313 = 129318
29 + 129289 = 129318
31 + 129287 = 129318
37 + 129281 = 129318
41 + 129277 = 129318
89 + 129229 = 129318
97 + 129221 = 129318
109 + 129209 = 129318

Showing the first eight; more decompositions exist.
