Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493444, here are decompositions:

67 + 31493377 = 31493444
97 + 31493347 = 31493444
193 + 31493251 = 31493444
313 + 31493131 = 31493444
397 + 31493047 = 31493444
523 + 31492921 = 31493444
607 + 31492837 = 31493444
643 + 31492801 = 31493444

Showing the first eight; more decompositions exist.
