Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497836, here are decompositions:

79 + 31497757 = 31497836
109 + 31497727 = 31497836
157 + 31497679 = 31497836
163 + 31497673 = 31497836
199 + 31497637 = 31497836
277 + 31497559 = 31497836
313 + 31497523 = 31497836
367 + 31497469 = 31497836

Showing the first eight; more decompositions exist.
