Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603302, here are decompositions:

41 + 31603261 = 31603302
43 + 31603259 = 31603302
53 + 31603249 = 31603302
109 + 31603193 = 31603302
163 + 31603139 = 31603302
179 + 31603123 = 31603302
191 + 31603111 = 31603302
193 + 31603109 = 31603302

Showing the first eight; more decompositions exist.
