Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504462, here are decompositions:

23 + 31504439 = 31504462
89 + 31504373 = 31504462
233 + 31504229 = 31504462
359 + 31504103 = 31504462
449 + 31504013 = 31504462
491 + 31503971 = 31504462
599 + 31503863 = 31504462
653 + 31503809 = 31504462

Showing the first eight; more decompositions exist.
