Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473286, here are decompositions:

3 + 31473283 = 31473286
23 + 31473263 = 31473286
83 + 31473203 = 31473286
113 + 31473173 = 31473286
179 + 31473107 = 31473286
359 + 31472927 = 31473286
419 + 31472867 = 31473286
479 + 31472807 = 31473286

Showing the first eight; more decompositions exist.
