Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496860, here are decompositions:

41 + 31496819 = 31496860
167 + 31496693 = 31496860
191 + 31496669 = 31496860
293 + 31496567 = 31496860
419 + 31496441 = 31496860
431 + 31496429 = 31496860
443 + 31496417 = 31496860
491 + 31496369 = 31496860

Showing the first eight; more decompositions exist.
