Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544408, here are decompositions:

37 + 31544371 = 31544408
61 + 31544347 = 31544408
97 + 31544311 = 31544408
127 + 31544281 = 31544408
229 + 31544179 = 31544408
241 + 31544167 = 31544408
277 + 31544131 = 31544408
331 + 31544077 = 31544408

Showing the first eight; more decompositions exist.
