Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452350, here are decompositions:

67 + 31452283 = 31452350
109 + 31452241 = 31452350
151 + 31452199 = 31452350
229 + 31452121 = 31452350
271 + 31452079 = 31452350
331 + 31452019 = 31452350
337 + 31452013 = 31452350
421 + 31451929 = 31452350

Showing the first eight; more decompositions exist.
