Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516532, here are decompositions:

13 + 31516519 = 31516532
31 + 31516501 = 31516532
109 + 31516423 = 31516532
199 + 31516333 = 31516532
331 + 31516201 = 31516532
349 + 31516183 = 31516532
373 + 31516159 = 31516532
379 + 31516153 = 31516532

Showing the first eight; more decompositions exist.
