Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492444, here are decompositions:

23 + 31492421 = 31492444
41 + 31492403 = 31492444
107 + 31492337 = 31492444
167 + 31492277 = 31492444
281 + 31492163 = 31492444
353 + 31492091 = 31492444
383 + 31492061 = 31492444
461 + 31491983 = 31492444

Showing the first eight; more decompositions exist.
