Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541234, here are decompositions:

61 + 31541173 = 31541234
73 + 31541161 = 31541234
163 + 31541071 = 31541234
313 + 31540921 = 31541234
367 + 31540867 = 31541234
397 + 31540837 = 31541234
421 + 31540813 = 31541234
541 + 31540693 = 31541234

Showing the first eight; more decompositions exist.
