Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450334, here are decompositions:

43 + 31450291 = 31450334
127 + 31450207 = 31450334
193 + 31450141 = 31450334
241 + 31450093 = 31450334
277 + 31450057 = 31450334
313 + 31450021 = 31450334
367 + 31449967 = 31450334
397 + 31449937 = 31450334

Showing the first eight; more decompositions exist.
