Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 140630, here are decompositions:

3 + 140627 = 140630
13 + 140617 = 140630
19 + 140611 = 140630
37 + 140593 = 140630
43 + 140587 = 140630
73 + 140557 = 140630
79 + 140551 = 140630
97 + 140533 = 140630

Showing the first eight; more decompositions exist.
