Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538134, here are decompositions:

3 + 31538131 = 31538134
71 + 31538063 = 31538134
101 + 31538033 = 31538134
137 + 31537997 = 31538134
263 + 31537871 = 31538134
311 + 31537823 = 31538134
443 + 31537691 = 31538134
503 + 31537631 = 31538134

Showing the first eight; more decompositions exist.
