Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558652, here are decompositions:

3 + 31558649 = 31558652
19 + 31558633 = 31558652
163 + 31558489 = 31558652
199 + 31558453 = 31558652
271 + 31558381 = 31558652
331 + 31558321 = 31558652
523 + 31558129 = 31558652
571 + 31558081 = 31558652

Showing the first eight; more decompositions exist.
