Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603576, here are decompositions:

23 + 31603553 = 31603576
89 + 31603487 = 31603576
149 + 31603427 = 31603576
233 + 31603343 = 31603576
317 + 31603259 = 31603576
383 + 31603193 = 31603576
419 + 31603157 = 31603576
467 + 31603109 = 31603576

Showing the first eight; more decompositions exist.
