Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522234, here are decompositions:

5 + 31522229 = 31522234
53 + 31522181 = 31522234
131 + 31522103 = 31522234
173 + 31522061 = 31522234
257 + 31521977 = 31522234
281 + 31521953 = 31522234
347 + 31521887 = 31522234
383 + 31521851 = 31522234

Showing the first eight; more decompositions exist.
