Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504296, here are decompositions:

67 + 31504229 = 31504296
107 + 31504189 = 31504296
113 + 31504183 = 31504296
163 + 31504133 = 31504296
167 + 31504129 = 31504296
193 + 31504103 = 31504296
199 + 31504097 = 31504296
283 + 31504013 = 31504296

Showing the first eight; more decompositions exist.
