Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544552, here are decompositions:

19 + 31544533 = 31544552
43 + 31544509 = 31544552
181 + 31544371 = 31544552
229 + 31544323 = 31544552
241 + 31544311 = 31544552
271 + 31544281 = 31544552
331 + 31544221 = 31544552
373 + 31544179 = 31544552

Showing the first eight; more decompositions exist.
