Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480498, here are decompositions:

107 + 31480391 = 31480498
131 + 31480367 = 31480498
149 + 31480349 = 31480498
239 + 31480259 = 31480498
419 + 31480079 = 31480498
449 + 31480049 = 31480498
479 + 31480019 = 31480498
617 + 31479881 = 31480498

Showing the first eight; more decompositions exist.
