Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614642, here are decompositions:

11 + 31614631 = 31614642
41 + 31614601 = 31614642
79 + 31614563 = 31614642
83 + 31614559 = 31614642
149 + 31614493 = 31614642
193 + 31614449 = 31614642
271 + 31614371 = 31614642
359 + 31614283 = 31614642

Showing the first eight; more decompositions exist.
