Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528626, here are decompositions:

5 + 31528621 = 31528626
13 + 31528613 = 31528626
47 + 31528579 = 31528626
53 + 31528573 = 31528626
67 + 31528559 = 31528626
79 + 31528547 = 31528626
127 + 31528499 = 31528626
167 + 31528459 = 31528626

Showing the first eight; more decompositions exist.
