Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603952, here are decompositions:

19 + 31603933 = 31603952
73 + 31603879 = 31603952
109 + 31603843 = 31603952
151 + 31603801 = 31603952
241 + 31603711 = 31603952
271 + 31603681 = 31603952
433 + 31603519 = 31603952
463 + 31603489 = 31603952

Showing the first eight; more decompositions exist.
