Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603452, here are decompositions:

59 + 31603393 = 31603452
71 + 31603381 = 31603452
109 + 31603343 = 31603452
191 + 31603261 = 31603452
193 + 31603259 = 31603452
311 + 31603141 = 31603452
313 + 31603139 = 31603452
373 + 31603079 = 31603452

Showing the first eight; more decompositions exist.
