Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544002, here are decompositions:

5 + 31543997 = 31544002
11 + 31543991 = 31544002
23 + 31543979 = 31544002
41 + 31543961 = 31544002
89 + 31543913 = 31544002
131 + 31543871 = 31544002
173 + 31543829 = 31544002
233 + 31543769 = 31544002

Showing the first eight; more decompositions exist.
