Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592174, here are decompositions:

13 + 31592161 = 31592174
127 + 31592047 = 31592174
181 + 31591993 = 31592174
307 + 31591867 = 31592174
331 + 31591843 = 31592174
337 + 31591837 = 31592174
463 + 31591711 = 31592174
487 + 31591687 = 31592174

Showing the first eight; more decompositions exist.
