Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598418, here are decompositions:

17 + 31598401 = 31598418
37 + 31598381 = 31598418
41 + 31598377 = 31598418
97 + 31598321 = 31598418
139 + 31598279 = 31598418
151 + 31598267 = 31598418
157 + 31598261 = 31598418
179 + 31598239 = 31598418

Showing the first eight; more decompositions exist.
