Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478602, here are decompositions:

3 + 31478599 = 31478602
131 + 31478471 = 31478602
173 + 31478429 = 31478602
191 + 31478411 = 31478602
251 + 31478351 = 31478602
269 + 31478333 = 31478602
293 + 31478309 = 31478602
431 + 31478171 = 31478602

Showing the first eight; more decompositions exist.
