Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568496, here are decompositions:

5 + 31568491 = 31568496
73 + 31568423 = 31568496
79 + 31568417 = 31568496
83 + 31568413 = 31568496
97 + 31568399 = 31568496
103 + 31568393 = 31568496
109 + 31568387 = 31568496
139 + 31568357 = 31568496

Showing the first eight; more decompositions exist.
