Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467152, here are decompositions:

19 + 31467133 = 31467152
163 + 31466989 = 31467152
331 + 31466821 = 31467152
421 + 31466731 = 31467152
433 + 31466719 = 31467152
439 + 31466713 = 31467152
463 + 31466689 = 31467152
523 + 31466629 = 31467152

Showing the first eight; more decompositions exist.
