Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583528, here are decompositions:

7 + 31583521 = 31583528
19 + 31583509 = 31583528
79 + 31583449 = 31583528
271 + 31583257 = 31583528
397 + 31583131 = 31583528
547 + 31582981 = 31583528
577 + 31582951 = 31583528
631 + 31582897 = 31583528

Showing the first eight; more decompositions exist.
