Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462020, here are decompositions:

13 + 31462007 = 31462020
17 + 31462003 = 31462020
41 + 31461979 = 31462020
43 + 31461977 = 31462020
59 + 31461961 = 31462020
71 + 31461949 = 31462020
97 + 31461923 = 31462020
101 + 31461919 = 31462020

Showing the first eight; more decompositions exist.
