Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538734, here are decompositions:

5 + 31538729 = 31538734
23 + 31538711 = 31538734
41 + 31538693 = 31538734
173 + 31538561 = 31538734
257 + 31538477 = 31538734
401 + 31538333 = 31538734
593 + 31538141 = 31538734
701 + 31538033 = 31538734

Showing the first eight; more decompositions exist.
