Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31614028, here are decompositions:

101 + 31613927 = 31614028
167 + 31613861 = 31614028
227 + 31613801 = 31614028
311 + 31613717 = 31614028
359 + 31613669 = 31614028
389 + 31613639 = 31614028
401 + 31613627 = 31614028
449 + 31613579 = 31614028

Showing the first eight; more decompositions exist.
