Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461542, here are decompositions:

19 + 31461523 = 31461542
61 + 31461481 = 31461542
139 + 31461403 = 31461542
181 + 31461361 = 31461542
193 + 31461349 = 31461542
199 + 31461343 = 31461542
241 + 31461301 = 31461542
313 + 31461229 = 31461542

Showing the first eight; more decompositions exist.
