Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547204, here are decompositions:

43 + 31547161 = 31547204
61 + 31547143 = 31547204
103 + 31547101 = 31547204
127 + 31547077 = 31547204
223 + 31546981 = 31547204
313 + 31546891 = 31547204
373 + 31546831 = 31547204
397 + 31546807 = 31547204

Showing the first eight; more decompositions exist.
