Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552322, here are decompositions:

13 + 31552309 = 31552322
19 + 31552303 = 31552322
421 + 31551901 = 31552322
463 + 31551859 = 31552322
541 + 31551781 = 31552322
601 + 31551721 = 31552322
709 + 31551613 = 31552322
1039 + 31551283 = 31552322

Showing the first eight; more decompositions exist.
