Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451734, here are decompositions:

3 + 31451731 = 31451734
5 + 31451729 = 31451734
11 + 31451723 = 31451734
23 + 31451711 = 31451734
137 + 31451597 = 31451734
173 + 31451561 = 31451734
563 + 31451171 = 31451734
701 + 31451033 = 31451734

Showing the first eight; more decompositions exist.
