Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583846, here are decompositions:

37 + 31583809 = 31583846
43 + 31583803 = 31583846
67 + 31583779 = 31583846
97 + 31583749 = 31583846
337 + 31583509 = 31583846
397 + 31583449 = 31583846
409 + 31583437 = 31583846
433 + 31583413 = 31583846

Showing the first eight; more decompositions exist.
