Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494862, here are decompositions:

53 + 31494809 = 31494862
149 + 31494713 = 31494862
173 + 31494689 = 31494862
251 + 31494611 = 31494862
281 + 31494581 = 31494862
353 + 31494509 = 31494862
359 + 31494503 = 31494862
383 + 31494479 = 31494862

Showing the first eight; more decompositions exist.
