Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576904, here are decompositions:

3 + 31576901 = 31576904
13 + 31576891 = 31576904
61 + 31576843 = 31576904
127 + 31576777 = 31576904
223 + 31576681 = 31576904
421 + 31576483 = 31576904
487 + 31576417 = 31576904
643 + 31576261 = 31576904

Showing the first eight; more decompositions exist.
