Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538054, here are decompositions:

7 + 31538047 = 31538054
73 + 31537981 = 31538054
151 + 31537903 = 31538054
193 + 31537861 = 31538054
211 + 31537843 = 31538054
307 + 31537747 = 31538054
313 + 31537741 = 31538054
337 + 31537717 = 31538054

Showing the first eight; more decompositions exist.
