Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544062, here are decompositions:

5 + 31544057 = 31544062
23 + 31544039 = 31544062
29 + 31544033 = 31544062
41 + 31544021 = 31544062
71 + 31543991 = 31544062
83 + 31543979 = 31544062
101 + 31543961 = 31544062
149 + 31543913 = 31544062

Showing the first eight; more decompositions exist.
