Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489126, here are decompositions:

29 + 31489097 = 31489126
47 + 31489079 = 31489126
83 + 31489043 = 31489126
89 + 31489037 = 31489126
167 + 31488959 = 31489126
359 + 31488767 = 31489126
479 + 31488647 = 31489126
563 + 31488563 = 31489126

Showing the first eight; more decompositions exist.
