Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446376, here are decompositions:

47 + 31446329 = 31446376
53 + 31446323 = 31446376
149 + 31446227 = 31446376
419 + 31445957 = 31446376
587 + 31445789 = 31446376
653 + 31445723 = 31446376
683 + 31445693 = 31446376
887 + 31445489 = 31446376

Showing the first eight; more decompositions exist.
