Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583312, here are decompositions:

31 + 31583281 = 31583312
43 + 31583269 = 31583312
181 + 31583131 = 31583312
331 + 31582981 = 31583312
421 + 31582891 = 31583312
823 + 31582489 = 31583312
991 + 31582321 = 31583312
1063 + 31582249 = 31583312

Showing the first eight; more decompositions exist.
