Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458598, here are decompositions:

5 + 31458593 = 31458598
11 + 31458587 = 31458598
71 + 31458527 = 31458598
167 + 31458431 = 31458598
179 + 31458419 = 31458598
359 + 31458239 = 31458598
401 + 31458197 = 31458598
467 + 31458131 = 31458598

Showing the first eight; more decompositions exist.
