Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504006, here are decompositions:

29 + 31503977 = 31504006
89 + 31503917 = 31504006
197 + 31503809 = 31504006
227 + 31503779 = 31504006
257 + 31503749 = 31504006
293 + 31503713 = 31504006
449 + 31503557 = 31504006
563 + 31503443 = 31504006

Showing the first eight; more decompositions exist.
