Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451694, here are decompositions:

37 + 31451657 = 31451694
97 + 31451597 = 31451694
107 + 31451587 = 31451694
167 + 31451527 = 31451694
173 + 31451521 = 31451694
191 + 31451503 = 31451694
233 + 31451461 = 31451694
257 + 31451437 = 31451694

Showing the first eight; more decompositions exist.
