Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462050, here are decompositions:

29 + 31462021 = 31462050
43 + 31462007 = 31462050
47 + 31462003 = 31462050
71 + 31461979 = 31462050
73 + 31461977 = 31462050
89 + 31461961 = 31462050
101 + 31461949 = 31462050
107 + 31461943 = 31462050

Showing the first eight; more decompositions exist.
