Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31451634, here are decompositions:

17 + 31451617 = 31451634
37 + 31451597 = 31451634
47 + 31451587 = 31451634
73 + 31451561 = 31451634
107 + 31451527 = 31451634
113 + 31451521 = 31451634
131 + 31451503 = 31451634
173 + 31451461 = 31451634

Showing the first eight; more decompositions exist.
