Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598292, here are decompositions:

13 + 31598279 = 31598292
31 + 31598261 = 31598292
53 + 31598239 = 31598292
79 + 31598213 = 31598292
101 + 31598191 = 31598292
113 + 31598179 = 31598292
149 + 31598143 = 31598292
151 + 31598141 = 31598292

Showing the first eight; more decompositions exist.
