Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612648, here are decompositions:

29 + 31612619 = 31612648
59 + 31612589 = 31612648
101 + 31612547 = 31612648
167 + 31612481 = 31612648
257 + 31612391 = 31612648
449 + 31612199 = 31612648
569 + 31612079 = 31612648
797 + 31611851 = 31612648

Showing the first eight; more decompositions exist.
