Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523654, here are decompositions:

3 + 31523651 = 31523654
7 + 31523647 = 31523654
181 + 31523473 = 31523654
193 + 31523461 = 31523654
307 + 31523347 = 31523654
433 + 31523221 = 31523654
523 + 31523131 = 31523654
541 + 31523113 = 31523654

Showing the first eight; more decompositions exist.
