Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626802, here are decompositions:

5 + 31626797 = 31626802
113 + 31626689 = 31626802
239 + 31626563 = 31626802
269 + 31626533 = 31626802
419 + 31626383 = 31626802
443 + 31626359 = 31626802
479 + 31626323 = 31626802
569 + 31626233 = 31626802

Showing the first eight; more decompositions exist.
