Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544600, here are decompositions:

13 + 31544587 = 31544600
67 + 31544533 = 31544600
229 + 31544371 = 31544600
277 + 31544323 = 31544600
379 + 31544221 = 31544600
421 + 31544179 = 31544600
433 + 31544167 = 31544600
523 + 31544077 = 31544600

Showing the first eight; more decompositions exist.
