Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541604, here are decompositions:

7 + 31541597 = 31541604
13 + 31541591 = 31541604
23 + 31541581 = 31541604
41 + 31541563 = 31541604
47 + 31541557 = 31541604
97 + 31541507 = 31541604
137 + 31541467 = 31541604
167 + 31541437 = 31541604

Showing the first eight; more decompositions exist.
