Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480134, here are decompositions:

5 + 31480129 = 31480134
17 + 31480117 = 31480134
31 + 31480103 = 31480134
43 + 31480091 = 31480134
73 + 31480061 = 31480134
113 + 31480021 = 31480134
173 + 31479961 = 31480134
277 + 31479857 = 31480134

Showing the first eight; more decompositions exist.
