Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498176, here are decompositions:

53 + 31498123 = 31498176
89 + 31498087 = 31498176
107 + 31498069 = 31498176
137 + 31498039 = 31498176
167 + 31498009 = 31498176
173 + 31498003 = 31498176
179 + 31497997 = 31498176
197 + 31497979 = 31498176

Showing the first eight; more decompositions exist.
