Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534444, here are decompositions:

3 + 31534441 = 31534444
17 + 31534427 = 31534444
101 + 31534343 = 31534444
173 + 31534271 = 31534444
197 + 31534247 = 31534444
257 + 31534187 = 31534444
521 + 31533923 = 31534444
653 + 31533791 = 31534444

Showing the first eight; more decompositions exist.
