Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532342, here are decompositions:

3 + 31532339 = 31532342
13 + 31532329 = 31532342
19 + 31532323 = 31532342
73 + 31532269 = 31532342
139 + 31532203 = 31532342
229 + 31532113 = 31532342
271 + 31532071 = 31532342
421 + 31531921 = 31532342

Showing the first eight; more decompositions exist.
