Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464236, here are decompositions:

3 + 31464233 = 31464236
43 + 31464193 = 31464236
157 + 31464079 = 31464236
277 + 31463959 = 31464236
379 + 31463857 = 31464236
409 + 31463827 = 31464236
439 + 31463797 = 31464236
457 + 31463779 = 31464236

Showing the first eight; more decompositions exist.
