Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463120, here are decompositions:

37 + 31463083 = 31463120
43 + 31463077 = 31463120
97 + 31463023 = 31463120
151 + 31462969 = 31463120
211 + 31462909 = 31463120
223 + 31462897 = 31463120
313 + 31462807 = 31463120
349 + 31462771 = 31463120

Showing the first eight; more decompositions exist.
