Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464862, here are decompositions:

41 + 31464821 = 31464862
53 + 31464809 = 31464862
131 + 31464731 = 31464862
281 + 31464581 = 31464862
353 + 31464509 = 31464862
419 + 31464443 = 31464862
461 + 31464401 = 31464862
503 + 31464359 = 31464862

Showing the first eight; more decompositions exist.
