Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446838, here are decompositions:

89 + 31446749 = 31446838
149 + 31446689 = 31446838
197 + 31446641 = 31446838
281 + 31446557 = 31446838
347 + 31446491 = 31446838
509 + 31446329 = 31446838
587 + 31446251 = 31446838
827 + 31446011 = 31446838

Showing the first eight; more decompositions exist.
