Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473500, here are decompositions:

13 + 31473487 = 31473500
43 + 31473457 = 31473500
103 + 31473397 = 31473500
283 + 31473217 = 31473500
313 + 31473187 = 31473500
337 + 31473163 = 31473500
349 + 31473151 = 31473500
433 + 31473067 = 31473500

Showing the first eight; more decompositions exist.
