Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462698, here are decompositions:

89 + 31462609 = 31462698
107 + 31462591 = 31462698
109 + 31462589 = 31462698
151 + 31462547 = 31462698
167 + 31462531 = 31462698
191 + 31462507 = 31462698
227 + 31462471 = 31462698
257 + 31462441 = 31462698

Showing the first eight; more decompositions exist.
