Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504412, here are decompositions:

61 + 31504351 = 31504412
109 + 31504303 = 31504412
193 + 31504219 = 31504412
211 + 31504201 = 31504412
223 + 31504189 = 31504412
229 + 31504183 = 31504412
283 + 31504129 = 31504412
439 + 31503973 = 31504412

Showing the first eight; more decompositions exist.
