Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538262, here are decompositions:

11 + 31538251 = 31538262
23 + 31538239 = 31538262
59 + 31538203 = 31538262
101 + 31538161 = 31538262
109 + 31538153 = 31538262
131 + 31538131 = 31538262
149 + 31538113 = 31538262
191 + 31538071 = 31538262

Showing the first eight; more decompositions exist.
