Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489252, here are decompositions:

5 + 31489247 = 31489252
23 + 31489229 = 31489252
59 + 31489193 = 31489252
71 + 31489181 = 31489252
83 + 31489169 = 31489252
173 + 31489079 = 31489252
281 + 31488971 = 31489252
293 + 31488959 = 31489252

Showing the first eight; more decompositions exist.
