Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458444, here are decompositions:

7 + 31458437 = 31458444
13 + 31458431 = 31458444
41 + 31458403 = 31458444
67 + 31458377 = 31458444
71 + 31458373 = 31458444
113 + 31458331 = 31458444
167 + 31458277 = 31458444
257 + 31458187 = 31458444

Showing the first eight; more decompositions exist.
