Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480050, here are decompositions:

29 + 31480021 = 31480050
31 + 31480019 = 31480050
89 + 31479961 = 31480050
101 + 31479949 = 31480050
103 + 31479947 = 31480050
193 + 31479857 = 31480050
229 + 31479821 = 31480050
233 + 31479817 = 31480050

Showing the first eight; more decompositions exist.
