Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498676, here are decompositions:

19 + 31498657 = 31498676
37 + 31498639 = 31498676
127 + 31498549 = 31498676
163 + 31498513 = 31498676
397 + 31498279 = 31498676
463 + 31498213 = 31498676
487 + 31498189 = 31498676
607 + 31498069 = 31498676

Showing the first eight; more decompositions exist.
