Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464750, here are decompositions:

19 + 31464731 = 31464750
41 + 31464709 = 31464750
101 + 31464649 = 31464750
131 + 31464619 = 31464750
173 + 31464577 = 31464750
179 + 31464571 = 31464750
193 + 31464557 = 31464750
241 + 31464509 = 31464750

Showing the first eight; more decompositions exist.
