Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597282, here are decompositions:

29 + 31597253 = 31597282
83 + 31597199 = 31597282
131 + 31597151 = 31597282
239 + 31597043 = 31597282
251 + 31597031 = 31597282
359 + 31596923 = 31597282
383 + 31596899 = 31597282
401 + 31596881 = 31597282

Showing the first eight; more decompositions exist.
