Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529894, here are decompositions:

3 + 31529891 = 31529894
13 + 31529881 = 31529894
223 + 31529671 = 31529894
271 + 31529623 = 31529894
337 + 31529557 = 31529894
373 + 31529521 = 31529894
463 + 31529431 = 31529894
541 + 31529353 = 31529894

Showing the first eight; more decompositions exist.
