Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479602, here are decompositions:

13 + 31479589 = 31479602
43 + 31479559 = 31479602
61 + 31479541 = 31479602
103 + 31479499 = 31479602
163 + 31479439 = 31479602
181 + 31479421 = 31479602
313 + 31479289 = 31479602
331 + 31479271 = 31479602

Showing the first eight; more decompositions exist.
