Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504316, here are decompositions:

13 + 31504303 = 31504316
97 + 31504219 = 31504316
127 + 31504189 = 31504316
229 + 31504087 = 31504316
433 + 31503883 = 31504316
463 + 31503853 = 31504316
643 + 31503673 = 31504316
673 + 31503643 = 31504316

Showing the first eight; more decompositions exist.
