Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498226, here are decompositions:

13 + 31498213 = 31498226
37 + 31498189 = 31498226
103 + 31498123 = 31498226
139 + 31498087 = 31498226
157 + 31498069 = 31498226
223 + 31498003 = 31498226
229 + 31497997 = 31498226
367 + 31497859 = 31498226

Showing the first eight; more decompositions exist.
