Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76642, here are decompositions:

11 + 76631 = 76642
101 + 76541 = 76642
131 + 76511 = 76642
149 + 76493 = 76642
179 + 76463 = 76642
239 + 76403 = 76642
263 + 76379 = 76642
353 + 76289 = 76642

Showing the first eight; more decompositions exist.
