Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504374, here are decompositions:

7 + 31504367 = 31504374
17 + 31504357 = 31504374
23 + 31504351 = 31504374
47 + 31504327 = 31504374
71 + 31504303 = 31504374
173 + 31504201 = 31504374
191 + 31504183 = 31504374
241 + 31504133 = 31504374

Showing the first eight; more decompositions exist.
