Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603852, here are decompositions:

23 + 31603829 = 31603852
101 + 31603751 = 31603852
113 + 31603739 = 31603852
131 + 31603721 = 31603852
239 + 31603613 = 31603852
491 + 31603361 = 31603852
509 + 31603343 = 31603852
593 + 31603259 = 31603852

Showing the first eight; more decompositions exist.
