Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483902, here are decompositions:

13 + 31483889 = 31483902
19 + 31483883 = 31483902
31 + 31483871 = 31483902
41 + 31483861 = 31483902
61 + 31483841 = 31483902
83 + 31483819 = 31483902
101 + 31483801 = 31483902
103 + 31483799 = 31483902

Showing the first eight; more decompositions exist.
