Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552434, here are decompositions:

5 + 31552429 = 31552434
13 + 31552421 = 31552434
31 + 31552403 = 31552434
41 + 31552393 = 31552434
47 + 31552387 = 31552434
83 + 31552351 = 31552434
131 + 31552303 = 31552434
163 + 31552271 = 31552434

Showing the first eight; more decompositions exist.
