Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590342, here are decompositions:

29 + 31590313 = 31590342
73 + 31590269 = 31590342
79 + 31590263 = 31590342
101 + 31590241 = 31590342
131 + 31590211 = 31590342
181 + 31590161 = 31590342
193 + 31590149 = 31590342
271 + 31590071 = 31590342

Showing the first eight; more decompositions exist.
