Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504100, here are decompositions:

3 + 31504097 = 31504100
13 + 31504087 = 31504100
127 + 31503973 = 31504100
139 + 31503961 = 31504100
349 + 31503751 = 31504100
367 + 31503733 = 31504100
373 + 31503727 = 31504100
457 + 31503643 = 31504100

Showing the first eight; more decompositions exist.
