Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504404, here are decompositions:

17 + 31504387 = 31504404
31 + 31504373 = 31504404
37 + 31504367 = 31504404
47 + 31504357 = 31504404
53 + 31504351 = 31504404
101 + 31504303 = 31504404
271 + 31504133 = 31504404
277 + 31504127 = 31504404

Showing the first eight; more decompositions exist.
