Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583294, here are decompositions:

13 + 31583281 = 31583294
37 + 31583257 = 31583294
157 + 31583137 = 31583294
163 + 31583131 = 31583294
271 + 31583023 = 31583294
313 + 31582981 = 31583294
397 + 31582897 = 31583294
661 + 31582633 = 31583294

Showing the first eight; more decompositions exist.
