Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156140, here are decompositions:

13 + 156127 = 156140
31 + 156109 = 156140
79 + 156061 = 156140
277 + 155863 = 156140
307 + 155833 = 156140
331 + 155809 = 156140
367 + 155773 = 156140
409 + 155731 = 156140

Showing the first eight; more decompositions exist.
