Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452958, here are decompositions:

107 + 31452851 = 31452958
227 + 31452731 = 31452958
239 + 31452719 = 31452958
281 + 31452677 = 31452958
359 + 31452599 = 31452958
419 + 31452539 = 31452958
431 + 31452527 = 31452958
461 + 31452497 = 31452958

Showing the first eight; more decompositions exist.
