Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139012, here are decompositions:

53 + 138959 = 139012
89 + 138923 = 139012
113 + 138899 = 139012
149 + 138863 = 139012
191 + 138821 = 139012
281 + 138731 = 139012
383 + 138629 = 139012
431 + 138581 = 139012

Showing the first eight; more decompositions exist.
