Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489602, here are decompositions:

31 + 31489571 = 31489602
61 + 31489541 = 31489602
83 + 31489519 = 31489602
113 + 31489489 = 31489602
139 + 31489463 = 31489602
191 + 31489411 = 31489602
211 + 31489391 = 31489602
239 + 31489363 = 31489602

Showing the first eight; more decompositions exist.
