Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504418, here are decompositions:

31 + 31504387 = 31504418
61 + 31504357 = 31504418
67 + 31504351 = 31504418
199 + 31504219 = 31504418
229 + 31504189 = 31504418
331 + 31504087 = 31504418
367 + 31504051 = 31504418
457 + 31503961 = 31504418

Showing the first eight; more decompositions exist.
