Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31481604, here are decompositions:

13 + 31481591 = 31481604
61 + 31481543 = 31481604
73 + 31481531 = 31481604
83 + 31481521 = 31481604
97 + 31481507 = 31481604
107 + 31481497 = 31481604
127 + 31481477 = 31481604
131 + 31481473 = 31481604

Showing the first eight; more decompositions exist.
