Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452244, here are decompositions:

3 + 31452241 = 31452244
11 + 31452233 = 31452244
41 + 31452203 = 31452244
71 + 31452173 = 31452244
107 + 31452137 = 31452244
113 + 31452131 = 31452244
251 + 31451993 = 31452244
443 + 31451801 = 31452244

Showing the first eight; more decompositions exist.
