Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576124, here are decompositions:

3 + 31576121 = 31576124
7 + 31576117 = 31576124
37 + 31576087 = 31576124
331 + 31575793 = 31576124
397 + 31575727 = 31576124
457 + 31575667 = 31576124
487 + 31575637 = 31576124
571 + 31575553 = 31576124

Showing the first eight; more decompositions exist.
