Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467242, here are decompositions:

13 + 31467229 = 31467242
43 + 31467199 = 31467242
61 + 31467181 = 31467242
73 + 31467169 = 31467242
109 + 31467133 = 31467242
139 + 31467103 = 31467242
349 + 31466893 = 31467242
421 + 31466821 = 31467242

Showing the first eight; more decompositions exist.
