Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496830, here are decompositions:

3 + 31496827 = 31496830
11 + 31496819 = 31496830
47 + 31496783 = 31496830
89 + 31496741 = 31496830
137 + 31496693 = 31496830
257 + 31496573 = 31496830
263 + 31496567 = 31496830
293 + 31496537 = 31496830

Showing the first eight; more decompositions exist.
