Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557332, here are decompositions:

3 + 31557329 = 31557332
139 + 31557193 = 31557332
193 + 31557139 = 31557332
211 + 31557121 = 31557332
223 + 31557109 = 31557332
409 + 31556923 = 31557332
421 + 31556911 = 31557332
463 + 31556869 = 31557332

Showing the first eight; more decompositions exist.
