Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541736, here are decompositions:

29 + 31541707 = 31541736
43 + 31541693 = 31541736
59 + 31541677 = 31541736
103 + 31541633 = 31541736
139 + 31541597 = 31541736
167 + 31541569 = 31541736
173 + 31541563 = 31541736
179 + 31541557 = 31541736

Showing the first eight; more decompositions exist.
