Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577332, here are decompositions:

41 + 31577291 = 31577332
71 + 31577261 = 31577332
173 + 31577159 = 31577332
251 + 31577081 = 31577332
383 + 31576949 = 31577332
401 + 31576931 = 31577332
431 + 31576901 = 31577332
443 + 31576889 = 31577332

Showing the first eight; more decompositions exist.
