Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584176, here are decompositions:

3 + 31584173 = 31584176
37 + 31584139 = 31584176
109 + 31584067 = 31584176
157 + 31584019 = 31584176
193 + 31583983 = 31584176
313 + 31583863 = 31584176
367 + 31583809 = 31584176
373 + 31583803 = 31584176

Showing the first eight; more decompositions exist.
