Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504184, here are decompositions:

97 + 31504087 = 31504184
211 + 31503973 = 31504184
223 + 31503961 = 31504184
331 + 31503853 = 31504184
337 + 31503847 = 31504184
373 + 31503811 = 31504184
433 + 31503751 = 31504184
457 + 31503727 = 31504184

Showing the first eight; more decompositions exist.
