Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504350, here are decompositions:

23 + 31504327 = 31504350
47 + 31504303 = 31504350
131 + 31504219 = 31504350
149 + 31504201 = 31504350
167 + 31504183 = 31504350
223 + 31504127 = 31504350
263 + 31504087 = 31504350
313 + 31504037 = 31504350

Showing the first eight; more decompositions exist.
