Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598214, here are decompositions:

13 + 31598201 = 31598214
23 + 31598191 = 31598214
71 + 31598143 = 31598214
73 + 31598141 = 31598214
113 + 31598101 = 31598214
157 + 31598057 = 31598214
181 + 31598033 = 31598214
227 + 31597987 = 31598214

Showing the first eight; more decompositions exist.
