Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455176, here are decompositions:

37 + 31455139 = 31455176
73 + 31455103 = 31455176
223 + 31454953 = 31455176
349 + 31454827 = 31455176
367 + 31454809 = 31455176
439 + 31454737 = 31455176
523 + 31454653 = 31455176
787 + 31454389 = 31455176

Showing the first eight; more decompositions exist.
