Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552468, here are decompositions:

47 + 31552421 = 31552468
197 + 31552271 = 31552468
239 + 31552229 = 31552468
257 + 31552211 = 31552468
419 + 31552049 = 31552468
449 + 31552019 = 31552468
491 + 31551977 = 31552468
509 + 31551959 = 31552468

Showing the first eight; more decompositions exist.
