Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31610976, here are decompositions:

83 + 31610893 = 31610976
109 + 31610867 = 31610976
197 + 31610779 = 31610976
269 + 31610707 = 31610976
337 + 31610639 = 31610976
347 + 31610629 = 31610976
389 + 31610587 = 31610976
457 + 31610519 = 31610976

Showing the first eight; more decompositions exist.
