Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499598, here are decompositions:

5 + 31499593 = 31499598
37 + 31499561 = 31499598
61 + 31499537 = 31499598
101 + 31499497 = 31499598
107 + 31499491 = 31499598
131 + 31499467 = 31499598
139 + 31499459 = 31499598
167 + 31499431 = 31499598

Showing the first eight; more decompositions exist.
