Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458850, here are decompositions:

29 + 31458821 = 31458850
53 + 31458797 = 31458850
89 + 31458761 = 31458850
131 + 31458719 = 31458850
149 + 31458701 = 31458850
257 + 31458593 = 31458850
263 + 31458587 = 31458850
419 + 31458431 = 31458850

Showing the first eight; more decompositions exist.
