Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480350, here are decompositions:

61 + 31480289 = 31480350
149 + 31480201 = 31480350
233 + 31480117 = 31480350
271 + 31480079 = 31480350
331 + 31480019 = 31480350
389 + 31479961 = 31480350
401 + 31479949 = 31480350
521 + 31479829 = 31480350

Showing the first eight; more decompositions exist.
