Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461486, here are decompositions:

5 + 31461481 = 31461486
29 + 31461457 = 31461486
59 + 31461427 = 31461486
73 + 31461413 = 31461486
83 + 31461403 = 31461486
137 + 31461349 = 31461486
193 + 31461293 = 31461486
233 + 31461253 = 31461486

Showing the first eight; more decompositions exist.
