Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31190, here are decompositions:

7 + 31183 = 31190
13 + 31177 = 31190
31 + 31159 = 31190
37 + 31153 = 31190
43 + 31147 = 31190
67 + 31123 = 31190
109 + 31081 = 31190
127 + 31063 = 31190

Showing the first eight; more decompositions exist.
