Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577050, here are decompositions:

41 + 31577009 = 31577050
59 + 31576991 = 31577050
83 + 31576967 = 31577050
101 + 31576949 = 31577050
149 + 31576901 = 31577050
311 + 31576739 = 31577050
347 + 31576703 = 31577050
431 + 31576619 = 31577050

Showing the first eight; more decompositions exist.
