Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498166, here are decompositions:

43 + 31498123 = 31498166
79 + 31498087 = 31498166
97 + 31498069 = 31498166
127 + 31498039 = 31498166
157 + 31498009 = 31498166
163 + 31498003 = 31498166
283 + 31497883 = 31498166
307 + 31497859 = 31498166

Showing the first eight; more decompositions exist.
