Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583012, here are decompositions:

31 + 31582981 = 31583012
61 + 31582951 = 31583012
193 + 31582819 = 31583012
283 + 31582729 = 31583012
379 + 31582633 = 31583012
499 + 31582513 = 31583012
523 + 31582489 = 31583012
541 + 31582471 = 31583012

Showing the first eight; more decompositions exist.
