Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523196, here are decompositions:

53 + 31523143 = 31523196
83 + 31523113 = 31523196
97 + 31523099 = 31523196
193 + 31523003 = 31523196
307 + 31522889 = 31523196
349 + 31522847 = 31523196
373 + 31522823 = 31523196
449 + 31522747 = 31523196

Showing the first eight; more decompositions exist.
