Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504416, here are decompositions:

29 + 31504387 = 31504416
43 + 31504373 = 31504416
59 + 31504357 = 31504416
89 + 31504327 = 31504416
113 + 31504303 = 31504416
197 + 31504219 = 31504416
227 + 31504189 = 31504416
233 + 31504183 = 31504416

Showing the first eight; more decompositions exist.
