Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462268, here are decompositions:

127 + 31462141 = 31462268
199 + 31462069 = 31462268
307 + 31461961 = 31462268
349 + 31461919 = 31462268
457 + 31461811 = 31462268
571 + 31461697 = 31462268
751 + 31461517 = 31462268
787 + 31461481 = 31462268

Showing the first eight; more decompositions exist.
