Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584332, here are decompositions:

139 + 31584193 = 31584332
193 + 31584139 = 31584332
313 + 31584019 = 31584332
349 + 31583983 = 31584332
421 + 31583911 = 31584332
523 + 31583809 = 31584332
631 + 31583701 = 31584332
673 + 31583659 = 31584332

Showing the first eight; more decompositions exist.
