Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552392, here are decompositions:

5 + 31552387 = 31552392
41 + 31552351 = 31552392
83 + 31552309 = 31552392
89 + 31552303 = 31552392
139 + 31552253 = 31552392
163 + 31552229 = 31552392
181 + 31552211 = 31552392
199 + 31552193 = 31552392

Showing the first eight; more decompositions exist.
