Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592138, here are decompositions:

139 + 31591999 = 31592138
181 + 31591957 = 31592138
229 + 31591909 = 31592138
271 + 31591867 = 31592138
541 + 31591597 = 31592138
601 + 31591537 = 31592138
661 + 31591477 = 31592138
691 + 31591447 = 31592138

Showing the first eight; more decompositions exist.
