Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523758, here are decompositions:

5 + 31523753 = 31523758
89 + 31523669 = 31523758
107 + 31523651 = 31523758
179 + 31523579 = 31523758
281 + 31523477 = 31523758
317 + 31523441 = 31523758
347 + 31523411 = 31523758
359 + 31523399 = 31523758

Showing the first eight; more decompositions exist.
