Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11642, here are decompositions:

139 + 11503 = 11642
151 + 11491 = 11642
199 + 11443 = 11642
313 + 11329 = 11642
331 + 11311 = 11642
523 + 11119 = 11642
571 + 11071 = 11642
733 + 10909 = 11642

Showing the first eight; more decompositions exist.
