Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552436, here are decompositions:

7 + 31552429 = 31552436
43 + 31552393 = 31552436
127 + 31552309 = 31552436
199 + 31552237 = 31552436
229 + 31552207 = 31552436
367 + 31552069 = 31552436
379 + 31552057 = 31552436
439 + 31551997 = 31552436

Showing the first eight; more decompositions exist.
