Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529346, here are decompositions:

67 + 31529279 = 31529346
73 + 31529273 = 31529346
89 + 31529257 = 31529346
97 + 31529249 = 31529346
103 + 31529243 = 31529346
127 + 31529219 = 31529346
179 + 31529167 = 31529346
197 + 31529149 = 31529346

Showing the first eight; more decompositions exist.
