Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544120, here are decompositions:

31 + 31544089 = 31544120
43 + 31544077 = 31544120
67 + 31544053 = 31544120
79 + 31544041 = 31544120
109 + 31544011 = 31544120
193 + 31543927 = 31544120
277 + 31543843 = 31544120
337 + 31543783 = 31544120

Showing the first eight; more decompositions exist.
