Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473152, here are decompositions:

43 + 31473109 = 31473152
223 + 31472929 = 31473152
313 + 31472839 = 31473152
379 + 31472773 = 31473152
541 + 31472611 = 31473152
673 + 31472479 = 31473152
859 + 31472293 = 31473152
1009 + 31472143 = 31473152

Showing the first eight; more decompositions exist.
