Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552654, here are decompositions:

11 + 31552643 = 31552654
101 + 31552553 = 31552654
167 + 31552487 = 31552654
233 + 31552421 = 31552654
251 + 31552403 = 31552654
383 + 31552271 = 31552654
401 + 31552253 = 31552654
443 + 31552211 = 31552654

Showing the first eight; more decompositions exist.
