Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452684, here are decompositions:

7 + 31452677 = 31452684
17 + 31452667 = 31452684
61 + 31452623 = 31452684
97 + 31452587 = 31452684
101 + 31452583 = 31452684
113 + 31452571 = 31452684
157 + 31452527 = 31452684
163 + 31452521 = 31452684

Showing the first eight; more decompositions exist.
