Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544004, here are decompositions:

7 + 31543997 = 31544004
13 + 31543991 = 31544004
17 + 31543987 = 31544004
43 + 31543961 = 31544004
97 + 31543907 = 31544004
101 + 31543903 = 31544004
127 + 31543877 = 31544004
131 + 31543873 = 31544004

Showing the first eight; more decompositions exist.
