Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534100, here are decompositions:

43 + 31534057 = 31534100
67 + 31534033 = 31534100
151 + 31533949 = 31534100
181 + 31533919 = 31534100
229 + 31533871 = 31534100
271 + 31533829 = 31534100
277 + 31533823 = 31534100
331 + 31533769 = 31534100

Showing the first eight; more decompositions exist.
