Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40988, here are decompositions:

61 + 40927 = 40988
109 + 40879 = 40988
139 + 40849 = 40988
229 + 40759 = 40988
349 + 40639 = 40988
379 + 40609 = 40988
397 + 40591 = 40988
457 + 40531 = 40988

Showing the first eight; more decompositions exist.
