Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544076, here are decompositions:

19 + 31544057 = 31544076
23 + 31544053 = 31544076
37 + 31544039 = 31544076
43 + 31544033 = 31544076
79 + 31543997 = 31544076
89 + 31543987 = 31544076
97 + 31543979 = 31544076
149 + 31543927 = 31544076

Showing the first eight; more decompositions exist.
