Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590434, here are decompositions:

13 + 31590421 = 31590434
37 + 31590397 = 31590434
157 + 31590277 = 31590434
193 + 31590241 = 31590434
223 + 31590211 = 31590434
313 + 31590121 = 31590434
373 + 31590061 = 31590434
397 + 31590037 = 31590434

Showing the first eight; more decompositions exist.
