Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444684, here are decompositions:

3 + 31444681 = 31444684
23 + 31444661 = 31444684
41 + 31444643 = 31444684
53 + 31444631 = 31444684
137 + 31444547 = 31444684
281 + 31444403 = 31444684
317 + 31444367 = 31444684
443 + 31444241 = 31444684

Showing the first eight; more decompositions exist.
