Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576614, here are decompositions:

31 + 31576583 = 31576614
73 + 31576541 = 31576614
103 + 31576511 = 31576614
131 + 31576483 = 31576614
137 + 31576477 = 31576614
197 + 31576417 = 31576614
211 + 31576403 = 31576614
241 + 31576373 = 31576614

Showing the first eight; more decompositions exist.
