Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534902, here are decompositions:

23 + 31534879 = 31534902
29 + 31534873 = 31534902
31 + 31534871 = 31534902
71 + 31534831 = 31534902
83 + 31534819 = 31534902
101 + 31534801 = 31534902
103 + 31534799 = 31534902
149 + 31534753 = 31534902

Showing the first eight; more decompositions exist.
