Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598274, here are decompositions:

7 + 31598267 = 31598274
13 + 31598261 = 31598274
47 + 31598227 = 31598274
61 + 31598213 = 31598274
73 + 31598201 = 31598274
83 + 31598191 = 31598274
131 + 31598143 = 31598274
137 + 31598137 = 31598274

Showing the first eight; more decompositions exist.
