Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462250, here are decompositions:

109 + 31462141 = 31462250
181 + 31462069 = 31462250
229 + 31462021 = 31462250
271 + 31461979 = 31462250
307 + 31461943 = 31462250
331 + 31461919 = 31462250
409 + 31461841 = 31462250
433 + 31461817 = 31462250

Showing the first eight; more decompositions exist.
