Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594402, here are decompositions:

3 + 31594399 = 31594402
29 + 31594373 = 31594402
71 + 31594331 = 31594402
131 + 31594271 = 31594402
239 + 31594163 = 31594402
251 + 31594151 = 31594402
269 + 31594133 = 31594402
353 + 31594049 = 31594402

Showing the first eight; more decompositions exist.
