Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552358, here are decompositions:

7 + 31552351 = 31552358
151 + 31552207 = 31552358
379 + 31551979 = 31552358
421 + 31551937 = 31552358
457 + 31551901 = 31552358
499 + 31551859 = 31552358
577 + 31551781 = 31552358
601 + 31551757 = 31552358

Showing the first eight; more decompositions exist.
