Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498534, here are decompositions:

5 + 31498529 = 31498534
17 + 31498517 = 31498534
71 + 31498463 = 31498534
107 + 31498427 = 31498534
113 + 31498421 = 31498534
167 + 31498367 = 31498534
191 + 31498343 = 31498534
227 + 31498307 = 31498534

Showing the first eight; more decompositions exist.
