Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604400, here are decompositions:

13 + 31604387 = 31604400
17 + 31604383 = 31604400
29 + 31604371 = 31604400
41 + 31604359 = 31604400
43 + 31604357 = 31604400
53 + 31604347 = 31604400
59 + 31604341 = 31604400
89 + 31604311 = 31604400

Showing the first eight; more decompositions exist.
