Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484552, here are decompositions:

19 + 31484533 = 31484552
103 + 31484449 = 31484552
139 + 31484413 = 31484552
193 + 31484359 = 31484552
199 + 31484353 = 31484552
271 + 31484281 = 31484552
313 + 31484239 = 31484552
349 + 31484203 = 31484552

Showing the first eight; more decompositions exist.
