Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473132, here are decompositions:

23 + 31473109 = 31473132
71 + 31473061 = 31473132
101 + 31473031 = 31473132
149 + 31472983 = 31473132
241 + 31472891 = 31473132
281 + 31472851 = 31473132
283 + 31472849 = 31473132
293 + 31472839 = 31473132

Showing the first eight; more decompositions exist.
