Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504482, here are decompositions:

29 + 31504453 = 31504482
43 + 31504439 = 31504482
109 + 31504373 = 31504482
131 + 31504351 = 31504482
179 + 31504303 = 31504482
263 + 31504219 = 31504482
281 + 31504201 = 31504482
293 + 31504189 = 31504482

Showing the first eight; more decompositions exist.
