Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603848, here are decompositions:

5 + 31603843 = 31603848
19 + 31603829 = 31603848
47 + 31603801 = 31603848
97 + 31603751 = 31603848
109 + 31603739 = 31603848
127 + 31603721 = 31603848
131 + 31603717 = 31603848
137 + 31603711 = 31603848

Showing the first eight; more decompositions exist.
