Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558410, here are decompositions:

11 + 31558399 = 31558410
19 + 31558391 = 31558410
29 + 31558381 = 31558410
31 + 31558379 = 31558410
73 + 31558337 = 31558410
83 + 31558327 = 31558410
89 + 31558321 = 31558410
101 + 31558309 = 31558410

Showing the first eight; more decompositions exist.
