Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544628, here are decompositions:

41 + 31544587 = 31544628
67 + 31544561 = 31544628
97 + 31544531 = 31544628
211 + 31544417 = 31544628
257 + 31544371 = 31544628
281 + 31544347 = 31544628
317 + 31544311 = 31544628
331 + 31544297 = 31544628

Showing the first eight; more decompositions exist.
