Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583702, here are decompositions:

43 + 31583659 = 31583702
61 + 31583641 = 31583702
181 + 31583521 = 31583702
193 + 31583509 = 31583702
349 + 31583353 = 31583702
379 + 31583323 = 31583702
421 + 31583281 = 31583702
433 + 31583269 = 31583702

Showing the first eight; more decompositions exist.
