Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567848, here are decompositions:

29 + 31567819 = 31567848
79 + 31567769 = 31567848
107 + 31567741 = 31567848
131 + 31567717 = 31567848
139 + 31567709 = 31567848
149 + 31567699 = 31567848
167 + 31567681 = 31567848
199 + 31567649 = 31567848

Showing the first eight; more decompositions exist.
