Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455110, here are decompositions:

7 + 31455103 = 31455110
79 + 31455031 = 31455110
139 + 31454971 = 31455110
157 + 31454953 = 31455110
229 + 31454881 = 31455110
283 + 31454827 = 31455110
373 + 31454737 = 31455110
409 + 31454701 = 31455110

Showing the first eight; more decompositions exist.
