Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597202, here are decompositions:

3 + 31597199 = 31597202
73 + 31597129 = 31597202
103 + 31597099 = 31597202
151 + 31597051 = 31597202
199 + 31597003 = 31597202
211 + 31596991 = 31597202
313 + 31596889 = 31597202
409 + 31596793 = 31597202

Showing the first eight; more decompositions exist.
