Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541598, here are decompositions:

7 + 31541591 = 31541598
17 + 31541581 = 31541598
29 + 31541569 = 31541598
41 + 31541557 = 31541598
71 + 31541527 = 31541598
89 + 31541509 = 31541598
131 + 31541467 = 31541598
149 + 31541449 = 31541598

Showing the first eight; more decompositions exist.
