Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583504, here are decompositions:

67 + 31583437 = 31583504
151 + 31583353 = 31583504
181 + 31583323 = 31583504
223 + 31583281 = 31583504
367 + 31583137 = 31583504
373 + 31583131 = 31583504
457 + 31583047 = 31583504
523 + 31582981 = 31583504

Showing the first eight; more decompositions exist.
