Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544378, here are decompositions:

7 + 31544371 = 31544378
31 + 31544347 = 31544378
67 + 31544311 = 31544378
97 + 31544281 = 31544378
157 + 31544221 = 31544378
199 + 31544179 = 31544378
211 + 31544167 = 31544378
337 + 31544041 = 31544378

Showing the first eight; more decompositions exist.
