Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554824, here are decompositions:

13 + 31554811 = 31554824
157 + 31554667 = 31554824
193 + 31554631 = 31554824
211 + 31554613 = 31554824
241 + 31554583 = 31554824
283 + 31554541 = 31554824
307 + 31554517 = 31554824
313 + 31554511 = 31554824

Showing the first eight; more decompositions exist.
