Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570734, here are decompositions:

61 + 31570673 = 31570734
67 + 31570667 = 31570734
131 + 31570603 = 31570734
157 + 31570577 = 31570734
227 + 31570507 = 31570734
233 + 31570501 = 31570734
337 + 31570397 = 31570734
397 + 31570337 = 31570734

Showing the first eight; more decompositions exist.
