Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139088, here are decompositions:

67 + 139021 = 139088
151 + 138937 = 139088
199 + 138889 = 139088
349 + 138739 = 139088
409 + 138679 = 139088
541 + 138547 = 139088
571 + 138517 = 139088
577 + 138511 = 139088

Showing the first eight; more decompositions exist.
