Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534552, here are decompositions:

59 + 31534493 = 31534552
251 + 31534301 = 31534552
281 + 31534271 = 31534552
311 + 31534241 = 31534552
353 + 31534199 = 31534552
383 + 31534169 = 31534552
431 + 31534121 = 31534552
449 + 31534103 = 31534552

Showing the first eight; more decompositions exist.
