Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489702, here are decompositions:

29 + 31489673 = 31489702
89 + 31489613 = 31489702
131 + 31489571 = 31489702
239 + 31489463 = 31489702
269 + 31489433 = 31489702
311 + 31489391 = 31489702
353 + 31489349 = 31489702
443 + 31489259 = 31489702

Showing the first eight; more decompositions exist.
