Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446674, here are decompositions:

67 + 31446607 = 31446674
307 + 31446367 = 31446674
313 + 31446361 = 31446674
421 + 31446253 = 31446674
433 + 31446241 = 31446674
463 + 31446211 = 31446674
541 + 31446133 = 31446674
577 + 31446097 = 31446674

Showing the first eight; more decompositions exist.
