Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589100, here are decompositions:

13 + 31589087 = 31589100
31 + 31589069 = 31589100
43 + 31589057 = 31589100
73 + 31589027 = 31589100
83 + 31589017 = 31589100
89 + 31589011 = 31589100
107 + 31588993 = 31589100
149 + 31588951 = 31589100

Showing the first eight; more decompositions exist.
