Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498758, here are decompositions:

17 + 31498741 = 31498758
101 + 31498657 = 31498758
167 + 31498591 = 31498758
199 + 31498559 = 31498758
211 + 31498547 = 31498758
229 + 31498529 = 31498758
241 + 31498517 = 31498758
331 + 31498427 = 31498758

Showing the first eight; more decompositions exist.
