Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504194, here are decompositions:

5 + 31504189 = 31504194
11 + 31504183 = 31504194
61 + 31504133 = 31504194
67 + 31504127 = 31504194
97 + 31504097 = 31504194
107 + 31504087 = 31504194
157 + 31504037 = 31504194
181 + 31504013 = 31504194

Showing the first eight; more decompositions exist.
