Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506704, here are decompositions:

7 + 31506697 = 31506704
127 + 31506577 = 31506704
181 + 31506523 = 31506704
193 + 31506511 = 31506704
283 + 31506421 = 31506704
331 + 31506373 = 31506704
337 + 31506367 = 31506704
373 + 31506331 = 31506704

Showing the first eight; more decompositions exist.
