Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498150, here are decompositions:

107 + 31498043 = 31498150
347 + 31497803 = 31498150
353 + 31497797 = 31498150
443 + 31497707 = 31498150
449 + 31497701 = 31498150
479 + 31497671 = 31498150
599 + 31497551 = 31498150
659 + 31497491 = 31498150

Showing the first eight; more decompositions exist.
