Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504476, here are decompositions:

23 + 31504453 = 31504476
37 + 31504439 = 31504476
89 + 31504387 = 31504476
103 + 31504373 = 31504476
109 + 31504367 = 31504476
149 + 31504327 = 31504476
173 + 31504303 = 31504476
257 + 31504219 = 31504476

Showing the first eight; more decompositions exist.
