Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620262, here are decompositions:

53 + 31620209 = 31620262
59 + 31620203 = 31620262
71 + 31620191 = 31620262
131 + 31620131 = 31620262
269 + 31619993 = 31620262
281 + 31619981 = 31620262
419 + 31619843 = 31620262
461 + 31619801 = 31620262

Showing the first eight; more decompositions exist.
