Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522606, here are decompositions:

23 + 31522583 = 31522606
53 + 31522553 = 31522606
83 + 31522523 = 31522606
113 + 31522493 = 31522606
173 + 31522433 = 31522606
233 + 31522373 = 31522606
293 + 31522313 = 31522606
359 + 31522247 = 31522606

Showing the first eight; more decompositions exist.
