Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603248, here are decompositions:

101 + 31603147 = 31603248
107 + 31603141 = 31603248
109 + 31603139 = 31603248
137 + 31603111 = 31603248
139 + 31603109 = 31603248
239 + 31603009 = 31603248
317 + 31602931 = 31603248
331 + 31602917 = 31603248

Showing the first eight; more decompositions exist.
