Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449722, here are decompositions:

43 + 31449679 = 31449722
103 + 31449619 = 31449722
151 + 31449571 = 31449722
223 + 31449499 = 31449722
229 + 31449493 = 31449722
313 + 31449409 = 31449722
349 + 31449373 = 31449722
433 + 31449289 = 31449722

Showing the first eight; more decompositions exist.
