Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583498, here are decompositions:

61 + 31583437 = 31583498
229 + 31583269 = 31583498
241 + 31583257 = 31583498
367 + 31583131 = 31583498
547 + 31582951 = 31583498
601 + 31582897 = 31583498
607 + 31582891 = 31583498
769 + 31582729 = 31583498

Showing the first eight; more decompositions exist.
