Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612480, here are decompositions:

89 + 31612391 = 31612480
167 + 31612313 = 31612480
173 + 31612307 = 31612480
239 + 31612241 = 31612480
257 + 31612223 = 31612480
281 + 31612199 = 31612480
359 + 31612121 = 31612480
401 + 31612079 = 31612480

Showing the first eight; more decompositions exist.
