Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522168, here are decompositions:

107 + 31522061 = 31522168
149 + 31522019 = 31522168
191 + 31521977 = 31522168
281 + 31521887 = 31522168
317 + 31521851 = 31522168
521 + 31521647 = 31522168
569 + 31521599 = 31522168
659 + 31521509 = 31522168

Showing the first eight; more decompositions exist.
