Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595532, here are decompositions:

139 + 31595393 = 31595532
149 + 31595383 = 31595532
281 + 31595251 = 31595532
313 + 31595219 = 31595532
359 + 31595173 = 31595532
431 + 31595101 = 31595532
523 + 31595009 = 31595532
541 + 31594991 = 31595532

Showing the first eight; more decompositions exist.
