Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622502, here are decompositions:

11 + 31622491 = 31622502
29 + 31622473 = 31622502
73 + 31622429 = 31622502
113 + 31622389 = 31622502
229 + 31622273 = 31622502
313 + 31622189 = 31622502
349 + 31622153 = 31622502
383 + 31622119 = 31622502

Showing the first eight; more decompositions exist.
