Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464206, here are decompositions:

13 + 31464193 = 31464206
19 + 31464187 = 31464206
127 + 31464079 = 31464206
139 + 31464067 = 31464206
313 + 31463893 = 31464206
349 + 31463857 = 31464206
379 + 31463827 = 31464206
409 + 31463797 = 31464206

Showing the first eight; more decompositions exist.
