Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484402, here are decompositions:

43 + 31484359 = 31484402
163 + 31484239 = 31484402
193 + 31484209 = 31484402
199 + 31484203 = 31484402
223 + 31484179 = 31484402
241 + 31484161 = 31484402
331 + 31484071 = 31484402
421 + 31483981 = 31484402

Showing the first eight; more decompositions exist.
