Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463144, here are decompositions:

7 + 31463137 = 31463144
61 + 31463083 = 31463144
67 + 31463077 = 31463144
211 + 31462933 = 31463144
313 + 31462831 = 31463144
337 + 31462807 = 31463144
373 + 31462771 = 31463144
397 + 31462747 = 31463144

Showing the first eight; more decompositions exist.
