Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460860, here are decompositions:

23 + 31460837 = 31460860
29 + 31460831 = 31460860
131 + 31460729 = 31460860
251 + 31460609 = 31460860
311 + 31460549 = 31460860
419 + 31460441 = 31460860
461 + 31460399 = 31460860
491 + 31460369 = 31460860

Showing the first eight; more decompositions exist.
