Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450754, here are decompositions:

31 + 31450723 = 31450754
151 + 31450603 = 31450754
211 + 31450543 = 31450754
271 + 31450483 = 31450754
331 + 31450423 = 31450754
367 + 31450387 = 31450754
463 + 31450291 = 31450754
547 + 31450207 = 31450754

Showing the first eight; more decompositions exist.
