Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622292, here are decompositions:

5 + 31622287 = 31622292
11 + 31622281 = 31622292
19 + 31622273 = 31622292
103 + 31622189 = 31622292
109 + 31622183 = 31622292
113 + 31622179 = 31622292
139 + 31622153 = 31622292
151 + 31622141 = 31622292

Showing the first eight; more decompositions exist.
