Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544044, here are decompositions:

3 + 31544041 = 31544044
5 + 31544039 = 31544044
11 + 31544033 = 31544044
23 + 31544021 = 31544044
47 + 31543997 = 31544044
53 + 31543991 = 31544044
83 + 31543961 = 31544044
131 + 31543913 = 31544044

Showing the first eight; more decompositions exist.
