Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548044, here are decompositions:

13 + 31548031 = 31548044
37 + 31548007 = 31548044
127 + 31547917 = 31548044
193 + 31547851 = 31548044
211 + 31547833 = 31548044
313 + 31547731 = 31548044
337 + 31547707 = 31548044
373 + 31547671 = 31548044

Showing the first eight; more decompositions exist.
