Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480598, here are decompositions:

157 + 31480441 = 31480598
229 + 31480369 = 31480598
397 + 31480201 = 31480598
577 + 31480021 = 31480598
769 + 31479829 = 31480598
829 + 31479769 = 31480598
859 + 31479739 = 31480598
1009 + 31479589 = 31480598

Showing the first eight; more decompositions exist.
