Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446542, here are decompositions:

103 + 31446439 = 31446542
181 + 31446361 = 31446542
313 + 31446229 = 31446542
331 + 31446211 = 31446542
409 + 31446133 = 31446542
601 + 31445941 = 31446542
613 + 31445929 = 31446542
691 + 31445851 = 31446542

Showing the first eight; more decompositions exist.
