Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460152, here are decompositions:

23 + 31460129 = 31460152
89 + 31460063 = 31460152
293 + 31459859 = 31460152
419 + 31459733 = 31460152
443 + 31459709 = 31460152
491 + 31459661 = 31460152
599 + 31459553 = 31460152
653 + 31459499 = 31460152

Showing the first eight; more decompositions exist.
