Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544384, here are decompositions:

13 + 31544371 = 31544384
37 + 31544347 = 31544384
61 + 31544323 = 31544384
73 + 31544311 = 31544384
103 + 31544281 = 31544384
163 + 31544221 = 31544384
307 + 31544077 = 31544384
331 + 31544053 = 31544384

Showing the first eight; more decompositions exist.
