Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534144, here are decompositions:

3 + 31534141 = 31534144
23 + 31534121 = 31534144
41 + 31534103 = 31534144
71 + 31534073 = 31534144
233 + 31533911 = 31534144
311 + 31533833 = 31534144
353 + 31533791 = 31534144
503 + 31533641 = 31534144

Showing the first eight; more decompositions exist.
