Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544354, here are decompositions:

7 + 31544347 = 31544354
31 + 31544323 = 31544354
43 + 31544311 = 31544354
73 + 31544281 = 31544354
223 + 31544131 = 31544354
277 + 31544077 = 31544354
313 + 31544041 = 31544354
367 + 31543987 = 31544354

Showing the first eight; more decompositions exist.
