Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614832, here are decompositions:

3 + 31614829 = 31614832
131 + 31614701 = 31614832
191 + 31614641 = 31614832
269 + 31614563 = 31614832
281 + 31614551 = 31614832
383 + 31614449 = 31614832
461 + 31614371 = 31614832
479 + 31614353 = 31614832

Showing the first eight; more decompositions exist.
