Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504154, here are decompositions:

67 + 31504087 = 31504154
103 + 31504051 = 31504154
181 + 31503973 = 31504154
193 + 31503961 = 31504154
223 + 31503931 = 31504154
271 + 31503883 = 31504154
307 + 31503847 = 31504154
313 + 31503841 = 31504154

Showing the first eight; more decompositions exist.
