Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31491414, here are decompositions:

13 + 31491401 = 31491414
61 + 31491353 = 31491414
83 + 31491331 = 31491414
107 + 31491307 = 31491414
127 + 31491287 = 31491414
131 + 31491283 = 31491414
151 + 31491263 = 31491414
181 + 31491233 = 31491414

Showing the first eight; more decompositions exist.
