Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473824, here are decompositions:

13 + 31473811 = 31473824
43 + 31473781 = 31473824
241 + 31473583 = 31473824
337 + 31473487 = 31473824
367 + 31473457 = 31473824
541 + 31473283 = 31473824
607 + 31473217 = 31473824
661 + 31473163 = 31473824

Showing the first eight; more decompositions exist.
