Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523102, here are decompositions:

3 + 31523099 = 31523102
151 + 31522951 = 31523102
229 + 31522873 = 31523102
409 + 31522693 = 31523102
433 + 31522669 = 31523102
439 + 31522663 = 31523102
643 + 31522459 = 31523102
661 + 31522441 = 31523102

Showing the first eight; more decompositions exist.
