Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461884, here are decompositions:

43 + 31461841 = 31461884
61 + 31461823 = 31461884
67 + 31461817 = 31461884
73 + 31461811 = 31461884
211 + 31461673 = 31461884
313 + 31461571 = 31461884
331 + 31461553 = 31461884
367 + 31461517 = 31461884

Showing the first eight; more decompositions exist.
