Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554524, here are decompositions:

7 + 31554517 = 31554524
13 + 31554511 = 31554524
31 + 31554493 = 31554524
61 + 31554463 = 31554524
163 + 31554361 = 31554524
241 + 31554283 = 31554524
283 + 31554241 = 31554524
541 + 31553983 = 31554524

Showing the first eight; more decompositions exist.
