Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576884, here are decompositions:

41 + 31576843 = 31576884
107 + 31576777 = 31576884
181 + 31576703 = 31576884
211 + 31576673 = 31576884
373 + 31576511 = 31576884
401 + 31576483 = 31576884
431 + 31576453 = 31576884
457 + 31576427 = 31576884

Showing the first eight; more decompositions exist.
