Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449022, here are decompositions:

5 + 31449017 = 31449022
113 + 31448909 = 31449022
131 + 31448891 = 31449022
281 + 31448741 = 31449022
383 + 31448639 = 31449022
401 + 31448621 = 31449022
419 + 31448603 = 31449022
443 + 31448579 = 31449022

Showing the first eight; more decompositions exist.
