Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452632, here are decompositions:

61 + 31452571 = 31452632
103 + 31452529 = 31452632
139 + 31452493 = 31452632
151 + 31452481 = 31452632
181 + 31452451 = 31452632
331 + 31452301 = 31452632
349 + 31452283 = 31452632
433 + 31452199 = 31452632

Showing the first eight; more decompositions exist.
