Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552066, here are decompositions:

17 + 31552049 = 31552066
47 + 31552019 = 31552066
89 + 31551977 = 31552066
107 + 31551959 = 31552066
239 + 31551827 = 31552066
263 + 31551803 = 31552066
383 + 31551683 = 31552066
467 + 31551599 = 31552066

Showing the first eight; more decompositions exist.
