Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544424, here are decompositions:

7 + 31544417 = 31544424
31 + 31544393 = 31544424
53 + 31544371 = 31544424
61 + 31544363 = 31544424
101 + 31544323 = 31544424
113 + 31544311 = 31544424
127 + 31544297 = 31544424
211 + 31544213 = 31544424

Showing the first eight; more decompositions exist.
