Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464574, here are decompositions:

3 + 31464571 = 31464574
17 + 31464557 = 31464574
131 + 31464443 = 31464574
173 + 31464401 = 31464574
233 + 31464341 = 31464574
293 + 31464281 = 31464574
431 + 31464143 = 31464574
653 + 31463921 = 31464574

Showing the first eight; more decompositions exist.
