Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88190, here are decompositions:

13 + 88177 = 88190
61 + 88129 = 88190
73 + 88117 = 88190
97 + 88093 = 88190
199 + 87991 = 88190
229 + 87961 = 88190
313 + 87877 = 88190
337 + 87853 = 88190

Showing the first eight; more decompositions exist.
