Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499174, here are decompositions:

13 + 31499161 = 31499174
37 + 31499137 = 31499174
67 + 31499107 = 31499174
97 + 31499077 = 31499174
151 + 31499023 = 31499174
181 + 31498993 = 31499174
211 + 31498963 = 31499174
277 + 31498897 = 31499174

Showing the first eight; more decompositions exist.
