Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504344, here are decompositions:

17 + 31504327 = 31504344
41 + 31504303 = 31504344
211 + 31504133 = 31504344
241 + 31504103 = 31504344
257 + 31504087 = 31504344
293 + 31504051 = 31504344
307 + 31504037 = 31504344
331 + 31504013 = 31504344

Showing the first eight; more decompositions exist.
