Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598202, here are decompositions:

11 + 31598191 = 31598202
23 + 31598179 = 31598202
59 + 31598143 = 31598202
61 + 31598141 = 31598202
101 + 31598101 = 31598202
173 + 31598029 = 31598202
191 + 31598011 = 31598202
193 + 31598009 = 31598202

Showing the first eight; more decompositions exist.
