Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529954, here are decompositions:

31 + 31529923 = 31529954
73 + 31529881 = 31529954
277 + 31529677 = 31529954
283 + 31529671 = 31529954
331 + 31529623 = 31529954
397 + 31529557 = 31529954
433 + 31529521 = 31529954
523 + 31529431 = 31529954

Showing the first eight; more decompositions exist.
