Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464120, here are decompositions:

41 + 31464079 = 31464120
53 + 31464067 = 31464120
59 + 31464061 = 31464120
73 + 31464047 = 31464120
89 + 31464031 = 31464120
157 + 31463963 = 31464120
179 + 31463941 = 31464120
199 + 31463921 = 31464120

Showing the first eight; more decompositions exist.
