Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454632, here are decompositions:

5 + 31454627 = 31454632
149 + 31454483 = 31454632
191 + 31454441 = 31454632
281 + 31454351 = 31454632
311 + 31454321 = 31454632
383 + 31454249 = 31454632
431 + 31454201 = 31454632
509 + 31454123 = 31454632

Showing the first eight; more decompositions exist.
