Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576126, here are decompositions:

5 + 31576121 = 31576126
59 + 31576067 = 31576126
89 + 31576037 = 31576126
227 + 31575899 = 31576126
233 + 31575893 = 31576126
293 + 31575833 = 31576126
359 + 31575767 = 31576126
383 + 31575743 = 31576126

Showing the first eight; more decompositions exist.
