Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531592, here are decompositions:

13 + 31531579 = 31531592
109 + 31531483 = 31531592
139 + 31531453 = 31531592
193 + 31531399 = 31531592
223 + 31531369 = 31531592
331 + 31531261 = 31531592
523 + 31531069 = 31531592
613 + 31530979 = 31531592

Showing the first eight; more decompositions exist.
