Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452076, here are decompositions:

83 + 31451993 = 31452076
107 + 31451969 = 31452076
167 + 31451909 = 31452076
239 + 31451837 = 31452076
269 + 31451807 = 31452076
347 + 31451729 = 31452076
353 + 31451723 = 31452076
419 + 31451657 = 31452076

Showing the first eight; more decompositions exist.
