Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583300, here are decompositions:

19 + 31583281 = 31583300
31 + 31583269 = 31583300
43 + 31583257 = 31583300
163 + 31583137 = 31583300
277 + 31583023 = 31583300
349 + 31582951 = 31583300
409 + 31582891 = 31583300
523 + 31582777 = 31583300

Showing the first eight; more decompositions exist.
