Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532206, here are decompositions:

3 + 31532203 = 31532206
89 + 31532117 = 31532206
239 + 31531967 = 31532206
389 + 31531817 = 31532206
479 + 31531727 = 31532206
557 + 31531649 = 31532206
683 + 31531523 = 31532206
1229 + 31530977 = 31532206

Showing the first eight; more decompositions exist.
