Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454624, here are decompositions:

37 + 31454587 = 31454624
127 + 31454497 = 31454624
163 + 31454461 = 31454624
193 + 31454431 = 31454624
241 + 31454383 = 31454624
433 + 31454191 = 31454624
463 + 31454161 = 31454624
541 + 31454083 = 31454624

Showing the first eight; more decompositions exist.
