Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540430, here are decompositions:

13 + 31540417 = 31540430
67 + 31540363 = 31540430
223 + 31540207 = 31540430
241 + 31540189 = 31540430
283 + 31540147 = 31540430
307 + 31540123 = 31540430
331 + 31540099 = 31540430
367 + 31540063 = 31540430

Showing the first eight; more decompositions exist.
