Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498194, here are decompositions:

5 + 31498189 = 31498194
43 + 31498151 = 31498194
71 + 31498123 = 31498194
83 + 31498111 = 31498194
107 + 31498087 = 31498194
151 + 31498043 = 31498194
191 + 31498003 = 31498194
197 + 31497997 = 31498194

Showing the first eight; more decompositions exist.
