Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523836, here are decompositions:

83 + 31523753 = 31523836
167 + 31523669 = 31523836
257 + 31523579 = 31523836
359 + 31523477 = 31523836
557 + 31523279 = 31523836
569 + 31523267 = 31523836
593 + 31523243 = 31523836
599 + 31523237 = 31523836

Showing the first eight; more decompositions exist.
