Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140690, here are decompositions:

7 + 140683 = 140690
13 + 140677 = 140690
31 + 140659 = 140690
61 + 140629 = 140690
73 + 140617 = 140690
79 + 140611 = 140690
97 + 140593 = 140690
103 + 140587 = 140690

Showing the first eight; more decompositions exist.
