Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576544, here are decompositions:

3 + 31576541 = 31576544
61 + 31576483 = 31576544
67 + 31576477 = 31576544
127 + 31576417 = 31576544
193 + 31576351 = 31576544
277 + 31576267 = 31576544
283 + 31576261 = 31576544
313 + 31576231 = 31576544

Showing the first eight; more decompositions exist.
