Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505954, here are decompositions:

31 + 31505923 = 31505954
223 + 31505731 = 31505954
331 + 31505623 = 31505954
421 + 31505533 = 31505954
433 + 31505521 = 31505954
523 + 31505431 = 31505954
661 + 31505293 = 31505954
811 + 31505143 = 31505954

Showing the first eight; more decompositions exist.
