Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558562, here are decompositions:

43 + 31558519 = 31558562
73 + 31558489 = 31558562
109 + 31558453 = 31558562
163 + 31558399 = 31558562
181 + 31558381 = 31558562
241 + 31558321 = 31558562
433 + 31558129 = 31558562
499 + 31558063 = 31558562

Showing the first eight; more decompositions exist.
