Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595442, here are decompositions:

59 + 31595383 = 31595442
71 + 31595371 = 31595442
79 + 31595363 = 31595442
163 + 31595279 = 31595442
191 + 31595251 = 31595442
199 + 31595243 = 31595442
223 + 31595219 = 31595442
233 + 31595209 = 31595442

Showing the first eight; more decompositions exist.
