Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7992, here are decompositions:

29 + 7963 = 7992
41 + 7951 = 7992
43 + 7949 = 7992
59 + 7933 = 7992
73 + 7919 = 7992
109 + 7883 = 7992
113 + 7879 = 7992
139 + 7853 = 7992

Showing the first eight; more decompositions exist.
