Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583474, here are decompositions:

37 + 31583437 = 31583474
61 + 31583413 = 31583474
151 + 31583323 = 31583474
193 + 31583281 = 31583474
337 + 31583137 = 31583474
523 + 31582951 = 31583474
577 + 31582897 = 31583474
1153 + 31582321 = 31583474

Showing the first eight; more decompositions exist.
