Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622430, here are decompositions:

41 + 31622389 = 31622430
53 + 31622377 = 31622430
61 + 31622369 = 31622430
83 + 31622347 = 31622430
137 + 31622293 = 31622430
149 + 31622281 = 31622430
157 + 31622273 = 31622430
173 + 31622257 = 31622430

Showing the first eight; more decompositions exist.
