Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464230, here are decompositions:

37 + 31464193 = 31464230
43 + 31464187 = 31464230
151 + 31464079 = 31464230
163 + 31464067 = 31464230
199 + 31464031 = 31464230
229 + 31464001 = 31464230
271 + 31463959 = 31464230
337 + 31463893 = 31464230

Showing the first eight; more decompositions exist.
