Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598410, here are decompositions:

29 + 31598381 = 31598410
47 + 31598363 = 31598410
83 + 31598327 = 31598410
89 + 31598321 = 31598410
131 + 31598279 = 31598410
149 + 31598261 = 31598410
197 + 31598213 = 31598410
269 + 31598141 = 31598410

Showing the first eight; more decompositions exist.
