Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90140, here are decompositions:

13 + 90127 = 90140
19 + 90121 = 90140
67 + 90073 = 90140
73 + 90067 = 90140
109 + 90031 = 90140
139 + 90001 = 90140
151 + 89989 = 90140
157 + 89983 = 90140

Showing the first eight; more decompositions exist.
