Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462040, here are decompositions:

19 + 31462021 = 31462040
37 + 31462003 = 31462040
61 + 31461979 = 31462040
79 + 31461961 = 31462040
97 + 31461943 = 31462040
199 + 31461841 = 31462040
223 + 31461817 = 31462040
229 + 31461811 = 31462040

Showing the first eight; more decompositions exist.
