Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452754, here are decompositions:

5 + 31452749 = 31452754
23 + 31452731 = 31452754
71 + 31452683 = 31452754
131 + 31452623 = 31452754
167 + 31452587 = 31452754
227 + 31452527 = 31452754
233 + 31452521 = 31452754
257 + 31452497 = 31452754

Showing the first eight; more decompositions exist.
