Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506056, here are decompositions:

67 + 31505989 = 31506056
73 + 31505983 = 31506056
97 + 31505959 = 31506056
397 + 31505659 = 31506056
433 + 31505623 = 31506056
457 + 31505599 = 31506056
487 + 31505569 = 31506056
523 + 31505533 = 31506056

Showing the first eight; more decompositions exist.
