Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552120, here are decompositions:

71 + 31552049 = 31552120
101 + 31552019 = 31552120
179 + 31551941 = 31552120
263 + 31551857 = 31552120
293 + 31551827 = 31552120
317 + 31551803 = 31552120
449 + 31551671 = 31552120
491 + 31551629 = 31552120

Showing the first eight; more decompositions exist.
