Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552418, here are decompositions:

31 + 31552387 = 31552418
67 + 31552351 = 31552418
109 + 31552309 = 31552418
181 + 31552237 = 31552418
211 + 31552207 = 31552418
349 + 31552069 = 31552418
421 + 31551997 = 31552418
439 + 31551979 = 31552418

Showing the first eight; more decompositions exist.
