Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541698, here are decompositions:

5 + 31541693 = 31541698
47 + 31541651 = 31541698
101 + 31541597 = 31541698
107 + 31541591 = 31541698
191 + 31541507 = 31541698
269 + 31541429 = 31541698
281 + 31541417 = 31541698
401 + 31541297 = 31541698

Showing the first eight; more decompositions exist.
