Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504206, here are decompositions:

5 + 31504201 = 31504206
17 + 31504189 = 31504206
23 + 31504183 = 31504206
73 + 31504133 = 31504206
79 + 31504127 = 31504206
103 + 31504103 = 31504206
109 + 31504097 = 31504206
193 + 31504013 = 31504206

Showing the first eight; more decompositions exist.
