Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552406, here are decompositions:

3 + 31552403 = 31552406
13 + 31552393 = 31552406
19 + 31552387 = 31552406
97 + 31552309 = 31552406
103 + 31552303 = 31552406
199 + 31552207 = 31552406
337 + 31552069 = 31552406
349 + 31552057 = 31552406

Showing the first eight; more decompositions exist.
