Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497662, here are decompositions:

61 + 31497601 = 31497662
103 + 31497559 = 31497662
139 + 31497523 = 31497662
193 + 31497469 = 31497662
199 + 31497463 = 31497662
271 + 31497391 = 31497662
349 + 31497313 = 31497662
379 + 31497283 = 31497662

Showing the first eight; more decompositions exist.
