Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547924, here are decompositions:

3 + 31547921 = 31547924
7 + 31547917 = 31547924
73 + 31547851 = 31547924
193 + 31547731 = 31547924
223 + 31547701 = 31547924
241 + 31547683 = 31547924
283 + 31547641 = 31547924
307 + 31547617 = 31547924

Showing the first eight; more decompositions exist.
