Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505704, here are decompositions:

3 + 31505701 = 31505704
11 + 31505693 = 31505704
47 + 31505657 = 31505704
71 + 31505633 = 31505704
137 + 31505567 = 31505704
257 + 31505447 = 31505704
317 + 31505387 = 31505704
383 + 31505321 = 31505704

Showing the first eight; more decompositions exist.
