Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461722, here are decompositions:

151 + 31461571 = 31461722
199 + 31461523 = 31461722
241 + 31461481 = 31461722
373 + 31461349 = 31461722
379 + 31461343 = 31461722
421 + 31461301 = 31461722
499 + 31461223 = 31461722
541 + 31461181 = 31461722

Showing the first eight; more decompositions exist.
