Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506050, here are decompositions:

19 + 31506031 = 31506050
61 + 31505989 = 31506050
67 + 31505983 = 31506050
127 + 31505923 = 31506050
229 + 31505821 = 31506050
241 + 31505809 = 31506050
283 + 31505767 = 31506050
313 + 31505737 = 31506050

Showing the first eight; more decompositions exist.
